Flakes and nix.channel.enable

[frozen.frog23]

i deleted $HOME/.nix-profile, $HOME/.nix-defexpr/ and the contents of /nix/var/nix/profiles/per-user/root/ (or should i also delete ../per-user/, there is nothing besides an empty root/ folder there?). also, my (other) /root/ folder (in /) is empty (?) when i tried cd / and sudo ls root/ there, so i didnt touch it. the dead symlinks that i mentioned are still there, though, in the /nix/store/…

anyway, the warnings are gone now and these folders are no longer being created (again), so thank you!!!

edit: SORRY i know this is gonna bump it, but i just wanna share something similarly interesting (this is for the future readers if my vaguely titled OP comes up first in search results…):

Use channels as flake inputs

I recently learned that it is possible to use nixpkgs channel releases in flake inputs. (Credits to TLATER): More specifically, is there a reason to use one over the other? How is the nixexpr.tar.xz release generated, and how does it differ from a normal git checkout? # channel release inputs.nixpkgs.url = "https://channels.nixos.org/nixos-unstable/nixexprs.tar.xz"; # git release inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
