Basically, we want to change from this:
# flake.nix
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
};
# ...
}to this:
# flake.nix
{
inputs = {
nixpkgs.url = "https://channels.nixos.org/nixos-unstable/nixexprs.tar.xz";
};
# ...
}Why? Less reliance on GitHub, which has been showing more and more signs of being unreliable with all of the recent news of GitHub going down arbitrarily. There's another benefit that the tarballs contain a cache that can be used with command-not-found, which could make nix-index obsolete. Minor change, might target it for this staging cycle.
Minor issue pertains to our current mechanism of syncing flake.lock revisions across projects, which relies on using a specific commit hash, which is NOT possible if we start using tarballs. That might pose an issue (see the envrc file in templates/ if you want to see what I'm talking about).
