Right. > So I need to give the system-path to operate on... to take actions on > it. I dont see how to get around that... Oh, you mean the system-wide profile? (i.e. /nix/var/nix/profiles/system) That's the root's profile. If you use `nix-env` as root, it will operate on that by default. You typically need elevated privileges, but it's probably possible to change permissions of that directory... --Vladimir _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl https://mailman.science.uu.nl/mailman/listinfo/nix-dev
