As far as I know most distributions today (and definitely Debian Woody) use a utility called mdadm to administer SoftwareRaid devices on a Linux system. mdadm can be obtained from

One major issue for me is that you can use, and mount both the dev/ataraid/d0 devices, and the /dev/hd devices. This makes for lots of fun in the Red Hat installer, and Cerberus.

Stupidity management for the superuser is a user space issue in Unix systems. If the RH installer does let you do stupid things, please bugzilla it.
