[Bug 1218032] Re: Ubiquity crashes finalizing install onto btrfs raid1.

[Toby Corkindale]

This bug is still present in 13.10 "Saucy".

The problem seems to be because update-grub calls grub-mkconfig, which
polls btrfs to find out the physical devices underlying the filesystem
-- and grub replies with TWO devices, because it's configured as raid1.
However passing both devices to grub-setup causes errors, especially
because they are separated by a newline.
