Subject: [PATCH] feat(scripts/liminix): fail HARD and support root prefixes

Now that we possess the levitation technology, it's necessary to support
root prefixes for rebuild otherwise we will just overwrite our RAM disk
configuration.

Also, to avoid any issue, let's fail hard and avoid rebooting while
being in levitation for nothing.
