Solved; Was: This ks script isn't working on CentOS 4.8... Should it?

If you try and run the script on a regular box, it fails. While you are working on fine tuning the script, run it on a regular box and verify that the file it creates that to test with initially before you move to the load testing situation.

I want to thank Hugh for the note on me being a bash dork and Terry for his cat suggestion. Thanks also to Chip and Tru for taking the time to respond. I got a working kickstart file now that, finally, handles underlying disks properly.

It took me forever to find a working sample of a logical kickstart script, so now that I have one working, I'd like to post it here, "for the record", in case someone else finds it trying to sort out how to do something similar down the road. :)
