Turns out, when selecting GNOME in choose-services call of (gnu tests
install), it triggers downloads during "guix system init ..." call.

I guess it's normal because the installer image does not contain those
packages. However, as there's no connection, it fails.

Not sure, we can go further?

In the meantime, here's a patch that helps dealing with installation
failures.

Thanks,

Mathieu
