nixpkgs/flake.nix
Eelco Dolstra 74e7ef35fe nix-daemon.nix: Add option nix.registry
This allows you to specify the system-wide flake registry. One use is
to pin 'nixpkgs' to the Nixpkgs version used to build the system:

  nix.registry.nixpkgs.flake = nixpkgs;

where 'nixpkgs' is a flake input. This ensures that commands like

  $ nix run nixpkgs#hello

pull in a minimum of additional store paths.

You can also use this to redirect flakes, e.g.

  nix.registry.nixpkgs.to = {
    type = "github";
    owner = "my-org";
    repo = "my-nixpkgs";
  };
