- During the evaluation of flakes a pethora of custom output attributes have evolved, which cause warnings on a
nix flake check
. There should be a way to silence certain warnings or to modularize/extend the check system to allow for custom checks (Extend `nix flake check` to support custom attributes · Issue #6453 · NixOS/nix · GitHub) - Some commands “expand” a flakeref to a store path, and fail if that doesn’t exist. They should be smart and build it, eg.
nix copy
Not directly nix related but tightly fits the ecosystem:
- An equivalent of
nix-collect-garbage
that only removes profiles, but does not do an actual garbage collect - A flake compatible
nixos-option
(or generally usable with 2.4, regardles of flakes or not)
