Due to fetchGit not checking if rev is an ancestor of ref (there is even a FIXME comment about it in the code), the cache repo might not have the ref even though it has the rev. This doesn't matter when submodule = false, but the submodule = true code blows up because it tries to fetch the (missing) ref from the cache repo. Fix this in the simplest way possible: fetch all refs from the local cache repo when submodules = true. TODO: Add tests.
Nix, the purely functional package manager
Nix is a new take on package management that is fairly unique. Because of its purity aspects, a lot of issues found in traditional package managers don't appear with Nix.
To find out more about the tool, usage and installation instructions, please read the manual, which is available on the Nix website at https://nixos.org/nix/manual.
