The kickstart disk partitioning tool is even dumber than they new GUI tool, only useful for "one-size-fits-all" cases where you also do not mind accidentally deleting the contents of all disks. (yes, open the machine, disconnect disks, install, reconnect disks, close the machine, thanks, but no thanks).
I've started using the disk-by-id option in my kickstarts to target specific disks in disk/fs related directives. A tip I got from Nico who suggested I use the %pre section to configure the disks exactly the way I want to. Works really well. My %pre even contains commands to reset the LVM on re-installs. Many thanks, Nico! Ken
