"uid-range" provides 65536 UIDs to a build and runs the build as root in its user namespace. "systemd-cgroup" allows the build to mount the systemd cgroup controller (needed for running systemd-nspawn and NixOS containers). Also, add a configuration option "auto-allocate-uids" which is needed to enable these features, and some experimental feature gates. So to enable support for containers you need the following in nix.conf: experimental-features = auto-allocate-uids systemd-cgroup auto-allocate-uids = true system-features = uid-range systemd-cgroup
