We already have separate tests for checking whether the ISO boots correctly, so it's not necessary to do that here. So now tests/installer.nix just tests nixos-install, from a regular NixOS VM that uses the host's Nix store. This makes running the tests more convenient because we don't have to build a new ISO after every change.
*** NixOS *** NixOS is a Linux distribution based on the purely functional package management system Nix. More information can be found at http://nixos.org/nixos and in the manual in doc/manual.
