If that wasn't clear, I meant to make the two drives into a single RAID 1,
*then* partition that for root, swap, and boot.

Trouble is, it's for this one box. Next box, or the one after, will be
happy with the kickstart as it is.

The solved part: I did the <alt-F2> and created the RAID 1. I went back to
the GUI, and tried to rescan... it didn't find it, didn't show any drives,
then it showed the two real drives... then it gagged, and crashed, and
rebooted. HOWEVER, when I tried the next time, anaconda's probing found
the RAID, and I'm installing now.
