-		  GNU LESSER GENERAL PUBLIC LICENSE
-		       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
- 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-[This is the first released version of the Lesser GPL.  It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
-  This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it.  You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
-  When we speak of free software, we are referring to freedom of use,
-not price.  Our General Public Licenses are designed to make sure that
-you have the freedom to distribute copies of free software (and charge
-for this service if you wish); that you receive source code or can get
-it if you want it; that you can change the software and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
-  To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights.  These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
-  For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you.  You must make sure that they, too, receive or can get the source
-code.  If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it.  And you must show them these terms so they know their rights.
-
-  We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
-  To protect each distributor, we want to make it very clear that
-there is no warranty for the free library.  Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
-  Finally, software patents pose a constant threat to the existence of
-any free program.  We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder.  Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
-  Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License.  This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License.  We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
-  When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library.  The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom.  The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
-  We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License.  It also provides other free software developers Less
-of an advantage over competing non-free programs.  These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries.  However, the Lesser license provides advantages in certain
-special circumstances.
-
-  For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard.  To achieve this, non-free programs must be
-allowed to use the library.  A more frequent case is that a free
-library does the same job as widely used non-free libraries.  In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
-  In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software.  For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
-  Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.  Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library".  The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
-		  GNU LESSER GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
-  A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
-  The "Library", below, refers to any such software library or work
-which has been distributed under these terms.  A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language.  (Hereinafter, translation is
-included without limitation in the term "modification".)
-
-  "Source code" for a work means the preferred form of the work for
-making modifications to it.  For a library, complete source code means
-all the source code for all modules it contains, plus any associated
-interface definition files, plus the scripts used to control compilation
-and installation of the library.
-
-  Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it).  Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
-  1. You may copy and distribute verbatim copies of the Library's
-complete source code as you receive it, in any medium, provided that
-you conspicuously and appropriately publish on each copy an
-appropriate copyright notice and disclaimer of warranty; keep intact
-all the notices that refer to this License and to the absence of any
-warranty; and distribute a copy of this License along with the
-Library.
-
-  You may charge a fee for the physical act of transferring a copy,
-and you may at your option offer warranty protection in exchange for a
-fee.
-
-  2. You may modify your copy or copies of the Library or any portion
-of it, thus forming a work based on the Library, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) The modified work must itself be a software library.
-
-    b) You must cause the files modified to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    c) You must cause the whole of the work to be licensed at no
-    charge to all third parties under the terms of this License.
-
-    d) If a facility in the modified Library refers to a function or a
-    table of data to be supplied by an application program that uses
-    the facility, other than as an argument passed when the facility
-    is invoked, then you must make a good faith effort to ensure that,
-    in the event an application does not supply such function or
-    table, the facility still operates, and performs whatever part of
-    its purpose remains meaningful.
-
-    (For example, a function in a library to compute square roots has
-    a purpose that is entirely well-defined independent of the
-    application.  Therefore, Subsection 2d requires that any
-    application-supplied function or table used by this function must
-    be optional: if the application does not supply it, the square
-    root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Library,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Library, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote
-it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library.  To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License.  (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.)  Do not make any other change in
-these notices.
-
-  Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
-  This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
-  4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you accompany
-it with the complete corresponding machine-readable source code, which
-must be distributed under the terms of Sections 1 and 2 above on a
-medium customarily used for software interchange.
-
-  If distribution of object code is made by offering access to copy
-from a designated place, then offering equivalent access to copy the
-source code from the same place satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library".  Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
-  However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library".  The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
-  When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library.  The
-threshold for this to be true is not precisely defined by law.
-
-  If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work.  (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
-  Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
-  6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
-  You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License.  You must supply a copy of this License.  If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License.  Also, you must do one
-of these things:
-
-    a) Accompany the work with the complete corresponding
-    machine-readable source code for the Library including whatever
-    changes were used in the work (which must be distributed under
-    Sections 1 and 2 above); and, if the work is an executable linked
-    with the Library, with the complete machine-readable "work that
-    uses the Library", as object code and/or source code, so that the
-    user can modify the Library and then relink to produce a modified
-    executable containing the modified Library.  (It is understood
-    that the user who changes the contents of definitions files in the
-    Library will not necessarily be able to recompile the application
-    to use the modified definitions.)
-
-    b) Use a suitable shared library mechanism for linking with the
-    Library.  A suitable mechanism is one that (1) uses at run time a
-    copy of the library already present on the user's computer system,
-    rather than copying library functions into the executable, and (2)
-    will operate properly with a modified version of the library, if
-    the user installs one, as long as the modified version is
-    interface-compatible with the version that the work was made with.
-
-    c) Accompany the work with a written offer, valid for at
-    least three years, to give the same user the materials
-    specified in Subsection 6a, above, for a charge no more
-    than the cost of performing this distribution.
-
-    d) If distribution of the work is made by offering access to copy
-    from a designated place, offer equivalent access to copy the above
-    specified materials from the same place.
-
-    e) Verify that the user has already received a copy of these
-    materials or that you have already sent this user a copy.
-
-  For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it.  However, as a special exception,
-the materials to be distributed need not include anything that is
-normally distributed (in either source or binary form) with the major
-components (compiler, kernel, and so on) of the operating system on
-which the executable runs, unless that component itself accompanies
-the executable.
-
-  It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system.  Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
-  7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
-    a) Accompany the combined library with a copy of the same work
-    based on the Library, uncombined with any other library
-    facilities.  This must be distributed under the terms of the
-    Sections above.
-
-    b) Give prominent notice with the combined library of the fact
-    that part of it is a work based on the Library, and explaining
-    where to find the accompanying uncombined form of the same work.
-
-  8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License.  Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library is void, and will automatically terminate your
-rights under this License.  However, parties who have received copies,
-or rights, from you under this License will not have their licenses
-terminated so long as such parties remain in full compliance.
-
-  9. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Library or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
-  10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-subject to these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties with
-this License.
-
-  11. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Library at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Library by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Library.
-
-If any portion of this section is held invalid or unenforceable under any
-particular circumstance, the balance of the section is intended to apply,
-and the section as a whole is intended to apply in other circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library under this License may add
-an explicit geographical distribution limitation excluding those countries,
-so that distribution is permitted only in or among countries not thus
-excluded.  In such case, this License incorporates the limitation as if
-written in the body of this License.
-
-  13. The Free Software Foundation may publish revised and/or new
-versions of the Lesser General Public License from time to time.
-Such new versions will be similar in spirit to the present version,
-but may differ in detail to address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Library
-specifies a version number of this License which applies to it and
-"any later version", you have the option of following the terms and
-conditions either of that version or of any later version published by
-the Free Software Foundation.  If the Library does not specify a
-license version number, you may choose any version ever published by
-the Free Software Foundation.
-
-  14. If you wish to incorporate parts of the Library into other free
-programs whose distribution conditions are incompatible with these,
-write to the author to ask for permission.  For software which is
-copyrighted by the Free Software Foundation, write to the Free
-Software Foundation; we sometimes make exceptions for this.  Our
-decision will be guided by the two goals of preserving the free status
-of all derivatives of our free software and of promoting the sharing
-and reuse of software generally.
-
-			    NO WARRANTY
-
-  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
-KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
-IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
-LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
-WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
-AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
-FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
-CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
-LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
-RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
-FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-           How to Apply These Terms to Your New Libraries
-
-  If you develop a new library, and you want it to be of the greatest
-possible use to the public, we recommend making it free software that
-everyone can redistribute and change.  You can do so by permitting
-redistribution under these terms (or, alternatively, under the terms of the
-ordinary General Public License).
-
-  To apply these terms, attach the following notices to the library.  It is
-safest to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least the
-"copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the library's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This library is free software; you can redistribute it and/or
-    modify it under the terms of the GNU Lesser General Public
-    License as published by the Free Software Foundation; either
-    version 2.1 of the License, or (at your option) any later version.
-
-    This library is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
-    Lesser General Public License for more details.
-
-    You should have received a copy of the GNU Lesser General Public
-    License along with this library; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
-
-Also add information on how to contact you by electronic and paper mail.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the library, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
-
-  <signature of Ty Coon>, 1 April 1990

-That's all there is to it!

-# Benchmarking scripts for Lix
-
-These are very much WIP, and have a few clumsy assumptions that we would
-somewhat rather be fixed, but we have committed them to let others be able to
-do benchmarking in the mean time.
-
-## Benchmarking procedure
-
-Build some Lixes you want to compare, by whichever means you wish.
-
-Get a computer that is not busy and *strongly preferably* is bare-metal or at
-least not a cloud VM (e.g. go make coffee when running benchmarks).
-
-From the root of a Lix checkout, run `./bench/bench.sh resultlink-one
-resultlink-two`, where `resultlink-one` and `resultlink-two` are the result
-links from the builds you want to test (they can be any directory with bin/nix
-in it, however).
-
-To get the summary again, run `./bench/summarize.jq bench/bench-*.json`.
-
-## Example results
-
-(vim tip: `:r !bench/summarize.jq bench/bench-*.json` to dump it directly into
-your editor)

-
-The first argument to `--arg`/`--argstr` must be a valid Nix identifier, i.e.
-`nix-build --arg config.allowUnfree true` is now rejected.
-
-This is because that invocation is a false friend since it doesn't set
-`{ config = { allowUnfree = true; }; }`, but `{ "config.allowUnfree" = true; }`.
-
-The idea is to change the behavior to the latter in the long-term. For that,
-non-identifiers started giving a warning since 2.92 and are now rejected to give people
-who depend on that a chance to notice and potentially weigh in on the discussion.

-The code used to query substituters for derivations has been rewritten slightly
-to take advantage of our asynchronous runtime. Such queries run for every build
-that could download from substituters and processes every derivation that isn't
-yet present on the local system. Previously Lix would use `http-connections` to
-limit query concurrency, even for modern caches that support HTTP/2 and have no
-limit on how many queries can be run concurrently on one single connection. Lix
-no longer does this, resulting in approximately 60% reduction in query time for
-medium-sized closures (e.g. NixOS system closures) during testing, although the
-exact number depends greatly on local network latency and generally improves as
-latency increases. Unlike previously setting `http-connections` to `1` or other
-low values no longer brings a massive penalty in query performance if the cache
-in use by the querying system supports HTTP/2 (as e.g. `cache.nixos.org` does).

-issues: [gh#12698, fj#885]
-cls: [3765]
-category: Fixes
-credits: [raito, emilazy]
----
-
-Previously, CA certificates were only installed at
-`/etc/ssl/certs/ca-certificates.crt` for sandboxed builds on Linux.
-
-This setup was insufficient in light of recent changes in `nixpkgs`, which now
-enforce HTTPS usage for `fetchurl`, even for fixed-output derivations, to
-mitigate confidentiality risks such as `netrc` or credentials leakage.
-`nixpkgs` still make use of a special package called `cacerts` which contains a
-copy of the CA certificates maintained by Nixpkgs and added as a reference for
-TLS-enabled fetchers.
-
-As a result, having a consistent and trusted certificate authority in all
-builder environments is becoming more essential.
-
-On `nix-darwin`, the `NIX_SSL_CERT_FILE` environment variable is always
-explicitly defined, but it is ignored by the sandbox setup.
-
-Simultaneously, Nix evaluates and propagates impure environment variables via
-`lib.proxyImpureEnvVars`, meaning that if `NIX_SSL_CERT_FILE` is set (which
-influences the default value for `ssl-cert-file`), it will be forwarded
-unchanged into the builder environment.
-
-However, on Linux, Nix also *copies* the CA file into the sandbox, creating a
-discrepancy between the value of `NIX_SSL_CERT_FILE` and the actual trusted
-certificate path used during the build.
-
-This divergence caused confusion and was partially addressed by attempts to
-whitelist the CA path in the Darwin sandbox (see cl/2906), but that approach
-involved a non-trivial path canonicalization step and is not as general as this one.
-
-To address this properly, we now emit a warning and override
-`NIX_SSL_CERT_FILE` inside the builder, explicitly pointing it to the CA file
-copied into the sandbox.
-
-This eliminates ambiguity between `NIX_SSL_CERT_FILE`
-and `ssl-cert-file`, ensuring consistent trust anchors across platforms.
-
-This warning might become a hard error as we figure out what to do regarding
-`lib.proxyImpureEnvVars` in nixpkgs.
-
-The behavior has been verified across sandboxed and unsandboxed builds on both
-Linux and Darwin.
-
-As a consequence of this change, approximately 500 KB of CA certificate data is
-now unconditionally copied into the build directory for fixed-output
-derivations.
-
-While this ensures consistent trust verification without having to restart the
-daemon after system upgrades, it may introduce a slight overhead in build
-performance. At present, no optimizations have been implemented to avoid this
-copy, but if this overhead proves noticeable in your workflows, please open an
-issue so we can evaluate and possibly implement different strategies to render
-trust anchors visible.

-synopsis: New cgroup delegation model
-issues: [fj#537, fj#77]
-cls: [3230]
-category: "Breaking Changes"
-credits: [raito, horrors, lheckemann]
----
-
-Builds using cgroups (i.e. `use-cgroups = true` and the experimental feature
-`cgroups`) now always delegate a cgroup tree to the sandbox.
-
-Compared to the original C++ Nix project, our delegation includes the
-`subtree_control` file as well, which means that the sandbox can disable
-certain controllers in its own cgroup tree.
-
-This is a breaking change because this requires the Nix daemon to run with an
-already delegated cgroup tree by the service manager.
-
-## How to setup the cgroup tree with systemd?
-
-systemd offers knobs to perform the required setup using:
-
-```
-[Service]
-Delegate=yes
-DelegateSubtree=supervisor
-```
-
-These directives are now included in our systemd packaging.
-
-## What about using Nix as root without connecting to the daemon?
-
-Builds run as `root` without connecting to the daemon relying on the cgroup
-feature are now broken, i.e.
-
-```console
-# nix-build --use-cgroups --sandbox ... # will not work
-```
-
-Consider doing instead:
-
-```console
-# systemd-run --same-dir --wait -p Delegate=yes -p DelegateSubgroup=supervisor nix-build --use-cgroups ...
-```

-## What about other service managers than systemd?
-
-systemd has a [documentation](https://systemd.io/CGROUP_DELEGATION/) on how to
-handle cgroup delegation from service management perspective.
-
-If your service manager adheres to systemd semantics, e.g. writing an extended
-attribute `user.delegate=1` on the delegated cgroup tree directory and moving
-the `nix-daemon` process inside a cgroup tree to respect the inner process
-rule, then, the feature will work as well.
-
-## Why is the cgroup feature still experimental?
-
-While the cgroup feature unlocks many use cases, its behavior and integration (e.g. user experience), especially at scale on build farms or in multi-tenant environments, are not yet fully matured. There’s also potential for deeper systemd integration (e.g. using slices and scopes) that has not been fully explored.
-
-To avoid locking in an unstable interface, we’re keeping the experimental flag until we have validated the feature across a broader range of scenarios, including but not limited to:
-
-* Nix as root
-* Hydra-style build farms
-* Forgejo CI runners
-* Shared remote builders

-issues: []
-cls: [3198]
-category: "Features"
-credits: [raito, delroth, horrors, winter]
----
-
-Ever tried interpolating a port number in Lix and ended up with something like this?
-
-```nix
-"http://${config.network.host}:${builtins.toString config.network.port}/"
-```
-
-You're not alone. Thousands of Lix users suffer every day from excessive `builtins.toString` syndrome. It’s 2025, and we still have to cast integers to use them in strings.
-
-To address this, Lix introduces the **`coerce-integers`** experimental feature. When enabled, interpolated integers within `"${...}"` are automatically coerced to strings. This allows writing:
-
-```nix
-"http://${config.network.host}:${config.network.port}/"
-```
-
-without additional conversion.
-
-To enable the feature, you need to add `coerce-integers` to your set of experimental features.
-
-### Stabilization criteria
-
-The `coerce-integers` feature is experimental and limited strictly to string interpolation (`"${...}"`). Before stabilization, the following must hold:
-
-1. **Interpolation-only**
-   Coercion must not occur outside interpolation. Expressions like `"" + 42` must continue to fail.
-
-2. **Expectation that no explicit cast are being observed**
-   Cases observing explicit coercion (e.g., via `tryEval` gadget or similar) are expected not to be load-bearing in actual production code.
-
-### Timeline for stabilization
-
-If the feature proves safe and is widely adopted across typical usage (e.g., actual configurations in the wild turning on the flag, non-trivial out-of-tree projects using it), the experimental flag will be removed **after six months of active use or two Lix releases**, whichever is longer.
-
-This avoids locking the feature in experimental status indefinitely, as happened with Flakes, while allowing time for validation and ecosystem integration.
-
-### What about coercing floats or more?
-
-Coercion beyond integers -- such as for floats or other types -- is **not planned**, even under an experimental flag. Questions like "what is the canonical string representation of a float?" involve subtle and context-dependent trade-offs. Without a robust and principled mechanism to define and audit such behavior, introducing broader coercion risks setting unintended and hard-to-reverse precedents. The scope of `coerce-integers` is intentionally narrow and will remain so.
-
-In terms of outlook, a proposal like https://git.lix.systems/lix-project/lix/issues/835 could pave the way for a better solution.

-For the sake of concision, we refer to `disallowedReferences` in what follows,

-Derivations can define *output checks* to reject unwanted dependencies, such as

-
-* **Legacy style**: `disallowedReferences = [ ... ]` in the environment.
-* **Structured attrs**: `outputChecks.<output>.disallowedReferences = [ ... ]`,
-  typically used in `__json`.
-
-Only the structured form supports derivations with multiple outputs.
-
-`nix develop` internally rewrites derivations to create development shells. It

-It may be necessary to use `builtins.seq` to force the impure operations to happen first if one wants to do impure operations inside a repl-overlays file in pure evaluation mode.

-When a build fails because of [`disallowedRequisites`](@docroot@/language/advanced-attributes.md#adv-attr-disallowedRequisites), the error message now includes the chain of references that led to the failure. This makes it easier to see in which derivations the chain can be broken, to resolve the problem.

-```

-
-When using e.g. [Snix's nar-bridge](https://snix.dev/docs/components/overview/#nar-bridge) via
-an `http`-store, Lix would create cache entries with a wrong URL to the NAR when uploading
-a store-path.
-
-This caused hard build failures for Hydra.
-
-Lix doesn't create these entries on upload anymore. Instead, it only removes negative cache entries.
-The cache entry for a narinfo is now created the first time, Lix queries the cache
-for the previously uploaded store-path again.

-Previously the pkg-config files distributed with Lix were only suitable for dynamic linkage, causing "undefined reference to…" linker errors when trying to link statically.
-Private dependency information has now been added to make static linkage work as expected without user intervention.
-In addition, relevant static libraries are now prelinked to avoid strange failures due to missing static initializers.

----
-
-In the Lix evaluator, **symbols** represent immutable strings, like those used
-for attribute names.
-
-In evaluator design, such strings are typically [**interned**](https://en.wikipedia.org/wiki/String_interning), stored uniquely
-to save memory, and Lix inherits this approach from the original C++ codebase.
-
-However, some builtins, like `builtins.attrNames`, must return a `Value` type
-that can represent any Nix value (strings, integers, lists, etc.).
-
-Before this change, these builtins would create lists of `Value` objects by
-allocating them through the garbage collector, copying the symbol’s string
-content each time.
-
-This allocation is unnecessary if the interned symbols themselves also hold a
-`Value` representation allocated outside the garbage collector, since these
-live for the full duration of evaluation.
-
-As a result, this reduces the number of allocations, leading to:
-
-* A significant drop in maximum [resident set memory](https://en.wikipedia.org/wiki/Resident_set_size) (RSS), with some large-scale
-  tests showing up to 11% (about 500 MiB) savings in large colmena deployments.
-* A slight decrease in CPU usage during Nix evaluations.
-
-This change is inspired by https://github.com/NixOS/nix/pull/13258 but the approach is different.
-
-**Note** : [`xokdvium`](https://github.com/xokdvium) is the rightful author of https://gerrit.lix.systems/c/lix/+/3300 and the credit was missed on our end during the development process. We are deeply sorry for this mistake.

-# Tuning Cores and Jobs
-
-Lix has two relevant settings with regards to how your CPU cores will
-be utilized: `cores` and `max-jobs`. This chapter will talk about what
-they are, how they interact, and their configuration trade-offs.
-
-  - `max-jobs`\
-    Dictates how many separate derivations will be built at the same
-    time. If you set this to zero, the local machine will do no
-    builds.  Lix will still substitute from binary caches, and build
-    remotely if remote builders are configured.
-
-  - `cores`\
-    Suggests how many cores each derivation should use. Similar to
-    `make -j`.
-
-The `cores` setting determines the value of
-`NIX_BUILD_CORES`. `NIX_BUILD_CORES` is equal to `cores`, unless
-`cores` equals `0`, in which case `NIX_BUILD_CORES` will be the total
-number of cores in the system.
-
-The maximum number of consumed cores is a simple multiplication,
-`max-jobs` \* `NIX_BUILD_CORES`.
-
-The balance on how to set these two independent variables depends upon
-each builder's workload and hardware. Here are a few example scenarios
-on a machine with 24 cores:
-
-| `max-jobs` | `cores` | `NIX_BUILD_CORES` | Maximum Processes | Result                                                                                                                                                                                                                                                                                 |

-# Verifying Build Reproducibility
-
-You can use Lix's `diff-hook` setting to compare build results. Note
-that this hook is only executed if the results differ; it is not used
-for determining if the results are the same.
-
-For purposes of demonstration, we'll use the following Nix file,
-`deterministic.nix` for testing:
-
-```nix
-let
-  inherit (import <nixpkgs> {}) runCommand;
-in {
-  stable = runCommand "stable" {} ''
-    touch $out
-  '';
-
-  unstable = runCommand "unstable" {} ''
-    echo $RANDOM > $out
-  '';
-}
-```
-
-Additionally, `nix.conf` contains:
-
-    diff-hook = /etc/nix/my-diff-hook
-    run-diff-hook = true
-
-where `/etc/nix/my-diff-hook` is an executable file containing:
-
-```bash
-#!/bin/sh
-exec >&2
-echo "For derivation $3:"
-/run/current-system/sw/bin/diff -r "$1" "$2"
-```
-
-The diff hook is executed by the same user and group who ran the build.
-However, the diff hook does not have write access to the store path just
-built.
-
-# Spot-Checking Build Determinism
-
-Verify a path which already exists in the Nix store by passing `--check`
-to the build command.
-
-If the build passes and is deterministic, Lix will exit with a status
-code of 0:
-
-```console
-$ nix-build ./deterministic.nix --attr stable
-this derivation will be built:
-  /nix/store/z98fasz2jqy9gs0xbvdj939p27jwda38-stable.drv

-/nix/store/yyxlzw3vqaas7wfp04g0b1xg51f2czgq-stable

-
-If the build is not deterministic, Lix will exit with a status code of
-1:
-
-```console

-not be deterministic: output '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable' differs
-```
-
-In the Lix daemon's log, we will now see:
-
-```
-For derivation /nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv:
-1c1
-< 8108
----
-> 30204
-```
-
-Using `--check` with `--keep-failed` will cause Lix to keep the second
-build's output in a special, `.check` path:
-
-```console
-$ nix-build ./deterministic.nix --attr unstable --check --keep-failed
-checking outputs of '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv'...
-note: keeping build directory '/tmp/nix-build-unstable.drv-0'

-from '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check'
-```
-
-In particular, notice the
-`/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check` output. Lix
-has copied the build results to that directory where you can examine it.

-
-`--check` is only usable if the derivation has been built on the system
-already. If the derivation has not been built Lix will fail with the

-# Remote Builds
-
-Lix supports remote builds, where a local Lix installation can forward
-Nix builds to other machines. This allows multiple builds to be
-performed in parallel and allows Lix to perform multi-platform builds in
-a semi-transparent way. For instance, if you perform a build for a
-`x86_64-darwin` on an `i686-linux` machine, Lix can automatically
-forward the build to a `x86_64-darwin` machine, if available.
-
-To forward a build to a remote machine, it’s required that the remote
-machine is accessible via SSH and that it has Nix installed. You can
-test whether connecting to the remote Nix instance works, e.g.
-
-```console
-$ nix store ping --store ssh://mac
-```
-
-will try to connect to the machine named `mac`. It is possible to
-specify an SSH identity file as part of the remote store URI, e.g.
-
-```console
-$ nix store ping --store ssh://mac?ssh-key=/home/alice/my-key
-```
-
-Since builds should be non-interactive, the key should not have a
-passphrase. Alternatively, you can load identities ahead of time into
-`ssh-agent` or `gpg-agent`.
-
-If you get the error
-
-```console
-bash: nix-store: command not found
-error: cannot connect to 'mac'
-```
-
-then you need to ensure that the `PATH` of non-interactive login shells
-contains Nix.
-
-> **Warning**
->
-> If you are building via the Lix daemon (default on Linux and macOS), it is the Lix daemon user account (that is, `root`) that should have SSH access to a user (not necessarily `root`) on the remote machine.
->
-> Furthermore, `root` needs to have the public host keys for the remote system in its `.ssh/known_hosts`.
-> To add them to `known_hosts` for root, do `ssh-keyscan USER@HOST | sudo tee -a ~root/.ssh/known_hosts`.
->
-> If you can’t or don’t want to configure `root` to be able to access the remote machine, you can use a private Nix store instead by passing e.g. `--store ~/my-nix` when running a Nix command from the local machine.
-
-The list of remote machines can be specified on the command line or in
-the Lix configuration file. The former is convenient for testing. For
-example, the following command allows you to build a derivation for
-`x86_64-darwin` on a Linux machine:
-
-```console
-$ uname
-Linux
-
-$ nix build --impure \
-  --expr '(with import <nixpkgs> { system = "x86_64-darwin"; }; runCommand "foo" {} "uname > $out")' \
-  --builders 'ssh://mac x86_64-darwin'
-[1/0/1 built, 0.0 MiB DL] building foo on ssh://mac
-
-$ cat ./result
-Darwin
-```
-
-It is possible to specify multiple builders separated by a semicolon or
-a newline, e.g.
-
-```console
-  --builders 'ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd'
-```
-
-Each machine specification consists of the following elements, separated
-by spaces. Only the first element is required. To leave a field at its
-default, set it to `-`.
-
-1.  The URI of the remote store in the format
-    `ssh://[username@]hostname[?port=<port>]`, e.g. `ssh://nix@mac` or `ssh://mac`.
-    If the ssh server is not listening on port 22 (e.g. port 1337 in this case)
-    the URI would be `ssh://nix@mac?port=1337`
-    For backward compatibility, `ssh://` may be omitted. The hostname
-    may be an alias defined in your `~/.ssh/config`.
-
-2.  A comma-separated list of Nix platform type identifiers, such as
-    `x86_64-darwin`. It is possible for a machine to support multiple
-    platform types, e.g., `i686-linux,x86_64-linux`. If omitted, this
-    defaults to the local platform type.
-
-3.  The SSH identity file to be used to log in to the remote machine. If
-    omitted, SSH will use its regular identities.
-
-4.  The maximum number of builds that Lix will execute in parallel on
-    the machine. Typically this should be equal to the number of CPU
-    cores. For instance, the machine `itchy` in the example will execute
-    up to 8 builds in parallel.
-
-5.  The “speed factor”, indicating the relative speed of the machine. If
-    there are multiple machines of the right type, Lix will prefer the
-    fastest, taking load into account.
-
-6.  A comma-separated list of *supported features*. If a derivation has
-    the `requiredSystemFeatures` attribute, then Lix will only perform
-    the derivation on a machine that has the specified features. For
-    instance, the attribute
-
-    ```nix
-    requiredSystemFeatures = [ "kvm" ];
-    ```
-
-    will cause the build to be performed on a machine that has the `kvm`
-    feature.
-
-7.  A comma-separated list of *mandatory features*. A machine will only
-    be used to build a derivation if all of the machine’s mandatory
-    features appear in the derivation’s `requiredSystemFeatures`
-    attribute.
-
-8.  The (base64-encoded) public host key of the remote machine. If omitted, SSH
-    will use its regular known-hosts file. Specifically, the field is calculated
-    via `base64 -w0 /etc/ssh/ssh_host_ed25519_key.pub`.
-
-For example, the machine specification
-
-    nix@scratchy.labs.cs.uu.nl  i686-linux      /home/nix/.ssh/id_scratchy_auto        8 1 kvm
-    nix@itchy.labs.cs.uu.nl     i686-linux      /home/nix/.ssh/id_scratchy_auto        8 2
-    nix@poochie.labs.cs.uu.nl   i686-linux      /home/nix/.ssh/id_scratchy_auto        1 2 kvm benchmark
-
-specifies several machines that can perform `i686-linux` builds.
-However, `poochie` will only do builds that have the attribute
-
-```nix
-requiredSystemFeatures = [ "benchmark" ];
-```
-
-or
-
-```nix
-requiredSystemFeatures = [ "benchmark" "kvm" ];
-```
-
-`itchy` cannot do builds that require `kvm`, but `scratchy` does support
-such builds. For regular builds, `itchy` will be preferred over
-`scratchy` because it has a higher speed factor.
-
-Remote builders can also be configured in `nix.conf`, e.g.
-
-    builders = ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd
-
-Finally, remote builders can be configured in a separate configuration
-file included in `builders` via the syntax `@file`. For example,
-
-    builders = @/etc/nix/machines
-
-causes the list of machines in `/etc/nix/machines` to be included. (This
-is the default.)
-
-If you want the builders to use caches, you likely want to set the
-option `builders-use-substitutes` in your local `nix.conf`.
-
-To build only on remote builders and disable building on the local
-machine, you can use the option `--max-jobs 0`.

-# Using the `post-build-hook`
-
-# Implementation Caveats
-
-Here we use the post-build hook to upload to a binary cache. This is a
-simple and working example, but it is not suitable for all use cases.
-
-The post build hook program runs after each executed build, and blocks
-the build loop. The build loop exits if the hook program fails.
-
-Concretely, this implementation will make Lix slow or unusable when the
-internet is slow or unreliable.
-
-A more advanced implementation might pass the store paths to a
-user-supplied daemon or queue for processing the store paths outside of
-the build loop.
-
-# Prerequisites
-
-This tutorial assumes you have [configured an S3-compatible binary
-cache](../package-management/s3-substituter.md), and that the `root`
-user's default AWS profile can upload to the bucket.
-
-# Set up a Signing Key
-
-Use `nix-store --generate-binary-cache-key` to create our public and
-private signing keys. We will sign paths with the private key, and
-distribute the public key for verifying the authenticity of the paths.
-
-```console
-# nix-store --generate-binary-cache-key example-nix-cache-1 /etc/nix/key.private /etc/nix/key.public
-# cat /etc/nix/key.public
-example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
-```
-
-Then update [`nix.conf`](../command-ref/conf-file.md) on any machine that will access the cache.
-Add the cache URL to [`substituters`](../command-ref/conf-file.md#conf-substituters) and the public key to [`trusted-public-keys`](../command-ref/conf-file.md#conf-trusted-public-keys):
-
-    substituters = https://cache.nixos.org/ s3://example-nix-cache
-    trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
-
-Machines that build for the cache must sign derivations using the private key.
-On those machines, add the path to the key file to the [`secret-key-files`](../command-ref/conf-file.md#conf-secret-key-files) field in their [`nix.conf`](../command-ref/conf-file.md):
-
-    secret-key-files = /etc/nix/key.private
-
-We will restart the Nix daemon in a later step.
-
-# Implementing the build hook
-
-Write the following script to `/etc/nix/upload-to-cache.sh`:
-
-```bash
-#!/bin/sh
-
-set -eu
-set -f # disable globbing
-export IFS=' '
-
-echo "Uploading paths" $OUT_PATHS
-exec nix copy --to "s3://example-nix-cache" $OUT_PATHS
-```
-
-> **Note**
->
-> The `$OUT_PATHS` variable is a space-separated list of Nix store
-> paths. In this case, we expect and want the shell to perform word
-> splitting to make each output path its own argument to `nix
-> store sign`. Nix guarantees the paths will not contain any spaces,
-> however a store path might contain glob characters. The `set -f`
-> disables globbing in the shell.
-
-Then make sure the hook program is executable by the `root` user:
-
-```console
-# chmod +x /etc/nix/upload-to-cache.sh
-```
-
-# Updating Lix Configuration
-
-Edit `/etc/nix/nix.conf` to run our hook, by adding the following
-configuration snippet at the end:
-
-    post-build-hook = /etc/nix/upload-to-cache.sh
-
-Then, restart the `nix-daemon`.
-
-# Testing
-
-Build any derivation, for example:
-
-```console
-$ nix-build --expr '(import <nixpkgs> {}).writeText "example" (builtins.toString builtins.currentTime)'
-this derivation will be built:
-  /nix/store/s4pnfbkalzy5qz57qs6yybna8wylkig6-example.drv
-building '/nix/store/s4pnfbkalzy5qz57qs6yybna8wylkig6-example.drv'...
-running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'...
-post-build-hook: Signing paths /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-post-build-hook: Uploading paths /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-/nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-```
-
-Then delete the path from the store, and try substituting it from the
-binary cache:
-
-```console
-$ rm ./result
-$ nix-store --delete /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-```
-
-Now, copy the path back from the cache:
-
-```console
-$ nix-store --realise /nix/store/ibcyipq5gf91838ldx40mjsp0b8w9n18-example
-copying path '/nix/store/m8bmqwrch6l3h8s0k3d673xpmipcdpsa-example from 's3://example-nix-cache'...
-warning: you did not specify '--add-root'; the result might be removed by the garbage collector
-/nix/store/m8bmqwrch6l3h8s0k3d673xpmipcdpsa-example
-```
-
-# Conclusion
-
-We now have a Lix installation configured to automatically sign and
-upload every local build to a remote binary cache.
-
-Before deploying this to production, be sure to consider the
-[implementation caveats](#implementation-caveats).

-This chapter describes how Nix works.
-It should help users understand why Lix behaves as it does, and it should help developers understand how to modify Lix and how to write similar tools.

-## Overview
-
-Nix consists of [hierarchical layers].

-
-At the top is the [command line interface](../command-ref/command-ref.md) that drives the underlying layers.
-
-The [Nix language](../language/index.md) evaluator transforms Nix expressions into self-contained *build plans*, which are used to derive *build results* from referenced *build inputs*.
-
-The command line interface and Nix expressions are what users deal with most.
-
-> **Note**
-> The Nix language itself does not have a notion of *packages* or *configurations*.
-> As far as we are concerned here, the inputs and results of a build plan are just data.
-
-Underlying the command line interface and the Nix language evaluator is the [Nix store](../glossary.md#gloss-store), a mechanism to keep track of build plans, data, and references between them.
-It can also execute build plans to produce new data, which are made available to the operating system as files.
-
-A build plan itself is a series of *build tasks*, together with their build inputs.
-
-> **Important**
-> A build task in Nix is called [derivation](../glossary.md#gloss-derivation).
-
-Each build task has a special build input executed as *build instructions* in order to perform the build.
-The result of a build task can be input to another build task.
-
-The following [data flow diagram] shows a build plan for illustration.
-Build inputs used as instructions to a build task are marked accordingly:

-# File System Object
-
-Nix implementations use a simplified model of the file system, which consists of file system objects.
-Every file system object is one of the following:
-
- - File
-
-   - A possibly empty sequence of bytes for contents
-   - A single boolean representing the [executable](https://en.m.wikipedia.org/wiki/File-system_permissions#Permissions) permission
-
- - Directory
-
-   Mapping of names to child file system objects
-
- - [Symbolic link](https://en.m.wikipedia.org/wiki/Symbolic_link)
-
-   An arbitrary string.
-   Nix implementations do not assign any semantics to symbolic links.
-
-File system objects and their children form a tree.
-A bare file or symlink can be a root file system object.
-
-Nix does not encode any other file system notions such as [hard links](https://en.m.wikipedia.org/wiki/Hard_link), [permissions](https://en.m.wikipedia.org/wiki/File-system_permissions), timestamps, or other metadata.
-
-## Examples of file system objects
-
-A plain file:
-
-```
-50 B, executable: false
-```
-
-An executable file:
-
-```
-122 KB, executable: true
-```
-
-A symlink:
-
-```
--> /usr/bin/sh
-```
-
-A directory with contents:
-
-```
-├── bin
-│   └── hello: 35 KB, executable: true
-└── share
-    ├── info
-    │   └── hello.info: 36 KB, executable: false
-    └── man
-        └── man1
-            └── hello.1.gz: 790 B, executable: false
-```
-
-A directory that contains a symlink and other directories:
-
-```
-├── bin -> share/go/bin
-├── nix-support/
-└── share/

-# Name
-
-`nix.conf` - Lix configuration file
-
-# Description
-
-Lix supports a variety of configuration settings, which are read from configuration files or taken as command line flags.
-
-## Configuration file
-
-By default Lix reads settings from the following places, in that order:
-
-1. The system-wide configuration file `sysconfdir/nix/nix.conf` (i.e. `/etc/nix/nix.conf` on most systems), or `$NIX_CONF_DIR/nix.conf` if [`NIX_CONF_DIR`](./env-common.md#env-NIX_CONF_DIR) is set.
-
-   Values loaded in this file are not forwarded to the Nix daemon.
-   The client assumes that the daemon has already loaded them.
-
-1. If [`NIX_USER_CONF_FILES`](./env-common.md#env-NIX_USER_CONF_FILES) is set, then each path separated by `:` will be loaded in reverse order.
-
-   Otherwise it will look for `nix/nix.conf` files in `XDG_CONFIG_DIRS` and `XDG_CONFIG_HOME`.
-   If unset, `XDG_CONFIG_DIRS` defaults to `/etc/xdg`, and `XDG_CONFIG_HOME` defaults to `$HOME/.config` as per [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html).
-
-1. If [`NIX_CONFIG`](./env-common.md#env-NIX_CONFIG) is set, its contents are treated as the contents of a configuration file.
-
-### File format
-
-Configuration files consist of `name = value` pairs, one per line.
-Comments start with a `#` character.
-
-Example:
-
-```
-keep-outputs = true       # Nice for developers
-keep-derivations = true   # Idem
-```
-
-Other files can be included with a line like `include <path>`.
-A missing file is an error unless `!include` is used instead.
-
-Paths in `include`s and option values are interpreted relative to the current configuration file.
-In user configuration files, paths starting with `~/` are tilde expanded (by replacing the tilde by the value of `$HOME`).
-
-Only user configuration files (like `$XDG_CONFIG_HOME/nix/nix.conf` or the files listed in `$NIX_USER_CONF_FILES`) can use tilde paths relative to your home directory.
-Configuration listed in the `$NIX_CONFIG` environment variable may not use relative paths.
-
-A configuration setting usually overrides any previous value.
-However, for settings that take a list of items, you can prefix the name of the setting by `extra-` to *append* to the previous value.
-
-For instance,
-
-```
-substituters = a b
-extra-substituters = c d
-```
-
-defines the `substituters` setting to be `a b c d`.
-
-Unknown option names are not an error, and are simply ignored with a warning.
-
-## Command line flags
-
-Configuration options can be set on the command line, overriding the values set in the [configuration file](#configuration-file):
-
-- Every configuration setting has corresponding command line flag (e.g. `--max-jobs 16`).
-  Boolean settings do not need an argument, and can be explicitly disabled with the `no-` prefix (e.g. `--keep-failed` and `--no-keep-failed`).
-
-  Unknown option names are invalid flags (unless there is already a flag with that name), and are rejected with an error.
-
-- The flag `--option <name> <value>` is interpreted exactly like a `<name> = <value>` in a setting file.
-
-  Unknown option names are ignored with a warning.
-
-The `extra-` prefix is supported for settings that take a list of items (e.g. `--extra-trusted users alice` or `--option extra-trusted-users alice`).

-# Common Environment Variables
-
-Most commands in Lix interpret the following environment variables:
-
-  - <span id="env-IN_NIX_SHELL">[`IN_NIX_SHELL`](#env-IN_NIX_SHELL)</span>\
-    Indicator that tells if the current environment was set up by
-    `nix-shell`. It can have the values `pure` or `impure`.
-
-  - <span id="env-NIX_PATH">[`NIX_PATH`](#env-NIX_PATH)</span>\
-    A colon-separated list of directories used to look up the location of Nix
-    expressions using [paths](@docroot@/language/values.md#type-path)
-    enclosed in angle brackets (i.e., `<path>`),
-    e.g. `/home/eelco/Dev:/etc/nixos`. It can be extended using the
-    [`-I` option](@docroot@/command-ref/opt-common.md#opt-I).
-
-    If `NIX_PATH` is not set at all, Lix will fall back to the following list in [impure](@docroot@/command-ref/conf-file.md#conf-pure-eval) and [unrestricted](@docroot@/command-ref/conf-file.md#conf-restrict-eval) evaluation mode:
-
-      1. `$HOME/.nix-defexpr/channels`
-      2. `nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixpkgs`
-      3. `/nix/var/nix/profiles/per-user/root/channels`
-
-    If `NIX_PATH` is set to an empty string, resolving search paths will always fail.
-    For example, attempting to use `<nixpkgs>` will produce:
-
-        error: file 'nixpkgs' was not found in the Nix search path
-
-  - <span id="env-NIX_IGNORE_SYMLINK_STORE">[`NIX_IGNORE_SYMLINK_STORE`](#env-NIX_IGNORE_SYMLINK_STORE)</span>\
-    Normally, the Nix store directory (typically `/nix/store`) is not
-    allowed to contain any symlink components. This is to prevent
-    “impure” builds. Builders sometimes “canonicalise” paths by
-    resolving all symlink components. Thus, builds on different machines
-    (with `/nix/store` resolving to different locations) could yield
-    different results. This is generally not a problem, except when
-    builds are deployed to machines where `/nix/store` resolves
-    differently. If you are sure that you’re not going to do that, you
-    can set `NIX_IGNORE_SYMLINK_STORE` to `1`.
-
-    Note that if you’re symlinking the Nix store so that you can put it
-    on another file system than the root file system, on Linux you’re
-    better off using `bind` mount points, e.g.,
-
-    ```console
-    $ mkdir /nix
-    $ mount -o bind /mnt/otherdisk/nix /nix
-    ```
-
-    Consult the mount 8 manual page for details.
-
-  - <span id="env-NIX_STORE_DIR">[`NIX_STORE_DIR`](#env-NIX_STORE_DIR)</span>\
-    Overrides the location of the Nix store (default `prefix/store`).
-
-  - <span id="env-NIX_DATA_DIR">[`NIX_DATA_DIR`](#env-NIX_DATA_DIR)</span>\
-    Overrides the location of the Lix static data directory (default
-    `prefix/share`).
-
-  - <span id="env-NIX_LOG_DIR">[`NIX_LOG_DIR`](#env-NIX_LOG_DIR)</span>\
-    Overrides the location of the Lix log directory (default
-    `prefix/var/log/nix`).
-
-  - <span id="env-NIX_STATE_DIR">[`NIX_STATE_DIR`](#env-NIX_STATE_DIR)</span>\
-    Overrides the location of the Lix state directory (default
-    `prefix/var/nix`).
-
-  - <span id="env-NIX_CONF_DIR">[`NIX_CONF_DIR`](#env-NIX_CONF_DIR)</span>\
-    Overrides the location of the system Lix configuration directory
-    (default `prefix/etc/nix`).
-
-  - <span id="env-NIX_CONFIG">[`NIX_CONFIG`](#env-NIX_CONFIG)</span>\
-    Applies settings from Lix configuration from the environment.
-    The content is treated as if it was read from a Lix configuration file.
-    Settings are separated by the newline character.
-
-  - <span id="env-NIX_USER_CONF_FILES">[`NIX_USER_CONF_FILES`](#env-NIX_USER_CONF_FILES)</span>\
-    Overrides the location of the Lix user configuration files to load from.
-
-    The default are the locations according to the [XDG Base Directory Specification].
-    See the [XDG Base Directories](#xdg-base-directories) sub-section for details.
-
-    The variable is treated as a list separated by the `:` token.
-
-  - <span id="env-TMPDIR">[`TMPDIR`](#env-TMPDIR)</span>\
-    Use the specified directory to store temporary files. In particular,
-    this includes temporary build directories; these can take up
-    substantial amounts of disk space. The default is `/tmp`.
-

-    If Nix has been configured to use the Boehm garbage collector, this
-    variable sets the initial size of the heap in bytes. It defaults to
-    384 MiB. Setting it to a low value reduces memory consumption, but
-    will increase runtime due to the overhead of garbage collection.

-## XDG Base Directories
-
-Lix follows the [XDG Base Directory Specification].
-
-For backwards compatibility, commands in Lix will follow the standard only when [`use-xdg-base-directories`] is enabled.
-[New Nix commands](@docroot@/command-ref/new-cli/nix.md) (experimental) conform to the standard by default.
-
-The following environment variables are used to determine locations of various state and configuration files:
-
-- `XDG_CONFIG_HOME` (default `~/.config`)
-- `XDG_STATE_HOME` (default `~/.local/state`)
-- `XDG_CACHE_HOME` (default `~/.cache`)
