builtins.fetchGit initializes a headless git repository in
~/.cache/nix, clones the
url passed to it and then pulls a checkout from it into
/nix/store for use. I have a local
nixpkgs clone and a lot of
builtins.fetchGit. Because of that the git repo in
.cache is taking up an additional 1GB. Is it possible to specify a local nixpkgs from which nix can pull out snapshots and use them.
One hackish way that I can think of is to move the whole
.git directory of my clone to
~/.cache/nix, make it headless and somehow setup git to use that repo for a directory. Has anyone done something like that?
