Even with LILO, it's easier to have a raw BIOS partition for /boot:
software raid4/5/6, pvmove, raid1, &tc. There are a lot of bad hacks
in lilo to support some of those things in some configurations, but
nothing clean. The most reliable way to bring things up is to install
grub or lilo in /boot (on [hs]da1) and possibly mirror the boot sector
and the boot partition to the second drive. However, on a
failed-drive, most motherboards can't reboot anyway so you're talking
manual intervention in either case. With a block-level mirror,
hopefully just yanking the first drive lets you boot off #2, and of
course once you hit initrd and raidstart, it handles the failed disk
gracefully, right? :)
