Yes.  This just means we'd have "set root=(/dev/foo)" statements in grub.cfg,
but those are just meant as a backward compatibility hack for pre-UUID GRUB
installs.

However, notice that after David Miller's remark about Sparc support, it's
probably better to:

  - Keep the backward compatibility hack.

  - Not remove device.map on Sparc yet (untill a better solution is available)

Uhm actually I'm not completely sure this would work, as multi-disk setups
have multiple values for initial $root.

Better just ignore this part ;-)
