Why is this option necessary? If we removed automated generation of
device.map, user can still call grub-mkdevicemap manually.
But first we'd need to figure out what we do with the "set root=xxx"
backward compatibility hack. Has it been a while long enough that
we can remove support for GRUB installs that didn't come with UUID
support?
If we don't do anything on grub-mkconfig side and remove device.map, we'll
end up with things like "set root=(/dev/sda1)" which is not just useless
but also utterly confusing.
