Either clone the nixpkgs repository or you can find a copy at `/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs`. > (4) How do I fix something if it is broken?

That's how I modify packages: I have a clone of the nixpkgs repository and I modify expressions there. Then I do `nix-env -i` (or whatever I need) with `-f <path_to_my_copy_of_nixpkgs>`. That tells Nix to use _my_ expressions. In case of `nixos-rebuild` there is `-I` flag. > > Cheers > Ben > -- > "Make it so they have to reboot after every typo." -- Scott Adams > > > _______________________________________________ > nix-dev mailing list > [email protected] > http://lists.science.uu.nl/mailman/listinfo/nix-dev >
