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 
(thus leaving the MBR nice and free).

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

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