are we to assume that your 'long story' involves this *not* being
hardware raid? so you're setting this up with mdraid? or what?
if mdraid, I'd probably boot the CD (or PXE) to rescue mode, use fdisk
and mdadm to partition and raid the drives as you like, then reboot the
CD/PXE into normal install mode, and install onto the md devices you
oh, and you normally build two mirrors (raid1) then stripe them together
(raid0) rather than the other way around.
