Bug#610184: grub-pc: superfluous RAID member not just for spares

Subject: grub-pc: superfluous RAID member not just for spares
Package: grub-pc
Version: 1.98+20100804-13

This machine doesn't have any spares; just a four-disk mirror for /boot (md0)
and a four-disk raid10 (md1) for everything else.

So, will this machine still boot, or do I need to downgrade grub? Previous
version did not spew errors.
