Only if the root partition is the same as the boot partition - or if we
effectively migrate the "root device?" prompt into the bootloader,
which seems like a Bad Idea because it means that root can't be on a
device the bootloader can't see.

So do I.  But I can't see it as practical in all situations.

The biggest reason I've seen is for it to automatically install
partition info for newly-inserted removable media and for new devices.
For new devices I don't think it's a big deal; having to wedgeconfig
after adding a device doesn't seem onerous to me.  For removable media
I see this as a relatively serious problem.
