If a boot drive is the same as a root drive, you are right. Otherwise we need 
to do so.

I think we have seen tons of examples with GRUB Legacy which may not be solved 
automatically in all cases. If one digs into the archive of bug-grub, I guess 
several cases would be found easily. With GRUB 2, we can avoid embedding BIOS 
drive numbers in many cases, using UUIDs or labels or files. But this does 
not always work, so I am afraid that we need to support, even if 
it is an evil necessity.
