[Bug 1069856] Re: error: cannot find a GRUB drive for . Check your device.map.

[Tv]

I still see this (or very similar errors) on 13.10, with / on btrfs
(multidevice sda3 & sdb3) and /boot on devicemapper raid1 (sda2 and
sdb2). Since my symptoms look cosmetical only, I haven't tried deleting
anything in /etc/grub.d.
