Which is exactly what I did. What I was pointing out was that Fedora's 
behaviour is *good*. In a hands-off scripted installation, like with 
kickstart, you don't get the chance to confirm your choices so it would 
be all too easy to destroy data. That it just ignores the "clear all 
partitions" directive in kickstart on devices with a RAID superblock 
seems prudent.
