Heh, would be nice...though I suppose it might be possible to install to a
RAID array directly, I wouldn't have the correct RAID driver as Potato
comes with a nearly unmodified 2.2 kernel.  Oh well.

That does make sense. as RAID-5 is a tad more complex.

Do I just need the /boot partition out there (with silo.conf if a few notes
I have seen are correct), or do I need more than that outside of the RAID-5
partition?

Thanks for the quick response!
