Actually, this can't work now.  After I added a sanity check (sorry, this
was necessary) to verify file reading work properly, everything is more
intermangled.

I'm not sure what would be the right approach.  Perhaps a flag in grub-probe
that means "please skip grub_guess_root_device, argument is a device, not a
path!" ?  This will let the sanity check know when it can't tell which file
you want to read.

Or perhaps something more radical that splits everything in different layers
(of exposed user commands) ?  But that could clutter the user with so many
commands.

Suggestions?
