I think I've been kind of stupid - obviously the device where the MBR resides
(which doesn't affect LVM in any way...) must be given. Sorry. Now, doing
vgdisplay or the like in this script isn't all that nice when setup-storage has
all the information anyway. This should have been fixed in
3.4~beta1+experimental12, where setup-storage includes the disks that make up a
volume group in $BOOT_DEVICE. I've also tried to simplify the 10-setup script
even further (well, the really simple version is in experimental13).

Could you give that one another try?

Thanks,
Michael
