Hmm, according to GRUB docs it may or may not be able to use RAID devices
directly, and alas set them up as appropriate; it will certainly depend on the
GRUB version, newer versions should be able to do this.

I thus committed version r4869, which does set the BOOT_* variables in all
cases, but uses the RAID/LVM device names, and does (for now) not resolve them
to the underlying disk partitions.

Could you please give this version a try and report the results? In case this
does not work the way I hope it does, we will need to do this manually, i.e.,
resolve the disk parition names and so on. Not that it would be so hard to do
within setup-storage, but the scripts will require updates as well, as you
described.

HTH,
Michael
