    Well, your kernels must be on a 0.90-superblocked RAID-0 or RAID-1
    device. It can't handle booting off 1.x superblocks nor RAID-[56]
    (not that I could really hope for the latter).

    But that's just /boot, not everything else.

    Of course the same is true of initramfs, which can give you the 1 kernel
    image back, too. (It's also nicer in that you can autoassemble
    e.g. LVM-on-RAID, or even LVM-on-RAID-over-nbd if you so desire.)
