The essential commands from the NixOS installer as a package With this package, you get the commands like nixos-generate-config and nixos-install that you would otherwise only find on a NixOS system, such as an installer image. This way, you can install NixOS using a machine that only has Nix. It also includes the manpages, which are important because the commands rely on those for providing --help.
