I suggest the following:
/dev/hda1 - 20M /boot
/dev/hda2 - rest of the disk

Same partitioning for /dev/hdc .

Then make /dev/hda2 and /dev/hdc2 a software RAID mirror which has LVM on=
 top=20
(thus leaving the MBR nice and free).

Install the Debian MBR (I'm sure it's available under other names for oth=
er=20
distributions) on both /dev/hda and /dev/hdc.  It'll load a LILO boot blo=
ck=20
from an active partition on the same drive by default.
Make /dev/hda1 and /dev/hdc1 active using fdisk or the LILO "activate"=20
program.
Then after running "lilo" do "cat /dev/hda1 > /dev/hdc1".  At this stage =
if=20
/dev/hda fails then swapping /dev/hdc to /dev/hda should result in a boot=
able=20
system!

I have CC'd John Coffman (current Lilo developer) on this email as I thin=
k=20
it'll interest him.  Please remove his name from the CC list if you are g=
oing=20
to make a non-LILO posting.
