So, if I maintain a set of changes to nixos and nixpkgs in /etc/nixos I have to build and activate nixos manually, rather than with nixos-rebuild?

It would be fancy if Hydra could tag a git repository with the correct combination of nixos and nixpkgs submodules for each succesful NixOS build. Then I could rebase my repos and take advantage of the hydra builds.
