This is no different from before.

Yes.

It is certainly a behavior we can improve upon. It's
rather annoying to get a panic on a typo. However,
we must remain cognizant of the fact that an immediate
hard failure is what's needed at times.

Maybe a good approach is to change to ".onfail retry"
and extend the root mount prompt with a reboot command,
so that the user/operator is does not have to worry
about typos *and* don't have to trigger a panic just
so that he/she can initiate a reboot.

Thoughts?
