  <title>Testing the Installer</title>
  <para>
    Building, burning, and booting from an installation CD is rather
    tedious, so here is a quick way to see if the installer works
    properly:
  </para>
  <programlisting>
# mount -t tmpfs none /mnt
# nixos-generate-config --root /mnt
$ nix-build '&lt;nixpkgs/nixos&gt;' -A config.system.build.nixos-install
# ./result/bin/nixos-install
</programlisting>
  <para>
    To start a login shell in the new NixOS installation in
    <literal>/mnt</literal>:
  </para>
  <programlisting>
$ nix-build '&lt;nixpkgs/nixos&gt;' -A config.system.build.nixos-enter
# ./result/bin/nixos-enter
</programlisting>
