likewise solved by kickstart.
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).
Using %pre in the kickstart file is the way to fix this, but you do need
to do all the work yourself. I suppose I could share our %pre section
which examines disks and decides which to install on (it waits for
confirmation if it can't determine the drive itself). The logic is
simply to look for the first drive which either has no partition table
or has a /boot directory (ie reinstall). No claims that this is perfect
in any way, we hacked it together over the years and it works for us
(with SL6).
For the post-config stuff we use %post to set our configuration
management system (cfengine) to run after reboot.
