This is an intractable problem - Linux does not know which disks you think
should be the system disks.

This was true even in the "good old /dev/hda days" if you had more than one IDE
controller. (system disk on the add-on "UDMA100" PCI card, data disks
on the on-board "UDMA33" ports).

Even if Linux could read your mind perfectly, when you run a kickstart that automatically
irreversibly erases disks, you better disconnect all the "wrong" disks first,
just in case you have a brain fart at the wrong moment.
