The runner mounts a persistent nix-store volume over /nix. The current nixos/nix image makes /etc/nix/nix.conf a symlink into /nix/store, and the volume does not hold that path, so the link dangles and appending to it fails before checkout: "/etc/nix/nix.conf: No such file or directory". Pass the settings in NIX_CONFIG instead. Without a config file Nix also falls back to build-users-group = nixbld, which the container lacks, so set it empty and turn the sandbox off, as the image config does. Assisted-by: Claude:opus-5-5
