Hi Lance,

I think the easiest route to your solution is to use %ksappend or
%include.  You can create a script that runs in %pre to generate the
customized portions of the kickstart, then %include that customization
via the include statement.  A step up from this concept is using a
tool like cobbler... check out its website if you have never heard of
it before.

Basic Concept
--

%pre

# script to detect hardware and spit out custom kickstart lines:
bash /root/ks_setup_drives.sh > /tmp/ks_drive_config.ks

.... then inside kickstart:

# include generated script:
%include /tmp/ks_drive_config.ks

I hope I am right that this behavior is consistent across older
releases of Anaconda?
