In NixOS, paths in the Nix store have a gid of either “root” (if built by a substitute) or “nixbld” (if built from source). This is inconsistent. They should probably be chowned to “root”, but “nixbld” should also be fine (since theyre not group writable), as long as it is consistently done.

The group almost never matters, but rpmbuild actually checks whether the source tarball is owned by root :-S
