In theory git hash should be enough, however nobody implemented a githash=".." attribute for fixed builds.
Thus nixprefetchurl can be used. I personally wrote "nix-repository-manager" which runs git clone/pull in a local directory. This way updating is "faster" if there are only some updates, and you can update multiple repositories at the same time. Eg I've assigned all "gimp" related repositories or haxe related repositories to "gimp_group" or "haxe_group" and update them in parallel by: nix-repository-manager 2 . --update-then-publish gimp_group haxe_group (update-then-publish updates archives and uploads them to my server) Downside is that you explicitly have to upload the tarball somewhere. grep nixpkgs for "REGION AUTO UPDATE". A second downside is that requires more "trust" to trust such archives :/ So yes, I really should update it one time to output fetchgit lines instead ..
