This does open RAID-5 systems up for a full-redundancy solution with
little loss in capacity... Allocate the first 5 or 10MB on each drive
in your array for /boot as an n-way RAID-1 mirror and write LILO to the
MBR of each. Then configure the remainder of each drive for RAID-5, and
with this technique you only lose 5(n-1) or 10(n-1)MB from your array
for boot redundancy. Yank the first drive out and the second one boots
fine. Rearrange the disks and no matter what, the first one in the
chain is bootable. With the partition autodetect configured correctly,
this would, I think, provide an almost perfect substitute for bootable
SW-RAID-5. Anyone see any reason why this might not be quite so
straightforward a solution? Just my half-nybble...
