Most probably, this is currently _not_ the case (assuming you want the
BIOS-style version and not EFI). I guess a simple "parted print" should help you
verify this. If the partition is set to bios_grub, you are fine; if it has the
flag "boot", it's an EFI boot volume. I think this will best be fixed by adding
a specific disklabel "gpt-bios" to setup-storage that deals with such specifics.
Doing so is not really hard, I would just like to make sure that it will see
some testing. If you're willing to dive into this, I'd happily prepare a patch
in the next few days.

Does that interfer in any way with the GPT stuff? Or is it just the possible
problems with grub?
