what you could do: 1. create a backup of all files 2. remove most stuff in / except /home/, /etc/nixos/, /etc/nix, /nix/store (among some paths i just didn't think about) 3. boot a rescue nixos live-stick 4. do a nixos-install with the config you already have this basically makes sure that your store sqlite database gets properly repopulated. after you booted into your new system, consider: nix-collect-garbage -d to get rid of unused /nix/store paths _______________________________________________ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
