James,

The problem was my kickstart file. I had been using one that I use with Koan/KVM with static IP's.

I grabbed all of the %pre and %post lines from the sample.ks and now it works as expected.

Thanks for your help.

Eric

Yes. Are you using the sample.ks file we ship or one you've created yourself? There should be a snippet in the %pre section which generates that file. When you get the error you're seeing, it means that file isn't being created. The typical cause of that file not being created is what I said before.

Use the command "cobbler system getks --name=sysname" to view the ks as it will be downloaded by the system and look for errors, especially in the %pre section.
