If you've your root partition over raid0, and the raid array gets
stuffed you can safely (well, you need to be careful ) boot from one
disk only (ignoring the raid array), fix the problem, rebuild the array
and boot again using /dev/md0 as root dir. The "worst" problem I've ever
had was my /etc/raidtab (I know I should use mdadm...) in lost&found due
to a fs problem. I advice to use grub instead of lilo as it is much more
flexible in case of problems...

In my opinion you don't get that much from having /boot outside the raid
array on i386 where the software raid code is now pretty stable.
