# adding a new file to staging is enough:
git add ./hosts/${new_host}.nix
# Test your new deployment:
sudo nixos-rebuild $new_host test
# A generic `rebuild` wrapper for `nix build` is provided
# bypassing the need for `nixos-rebuild`.
# Usage: rebuild [host] {switch|boot|test|dry-activate}
# where `host` is any file living in the `./hosts` directory
# Test your new deployment; this will be run as root:
rebuild $new_host test
# You may wish to start by creating a user:
mkdir users/new-user && $EDITOR users/new-user/default.nix

sudo nixos-rebuild $new_host switch
rebuild $new_host switch
