I don't know. I'm sure DISK => partitions => RAID => partitions will
work - that's what I was suggesting Stefan should do to use 1.2
metadata. You can have LVM in the mix too. Oh and don't forget the
filesystem right at the end. It may be possible to get it to support
multi-level RAID but I haven't tried - I try to keep it simple with DISK
=> partition => RAID-1 => ext2; it's enough bother getting all the other
mess taken care of in the initrd and Linux, without doing it in GRUB too!
Cheers,
John.
