Using the same kickstart info for DVD and network installs?

[Toralf Lund <toralf@xxxxxxxxxxxxxx>]

I have a standard kickstart file for installation of a "correct" setup 
across the network. Now I want to support DVD installation as well (but 
also keep the network option.) I have created a kickstart file which is 
identical to the other one, except the install source is different, but 
I really don't like maintaining two different files that are nearly the 
same. Is there a better way to organise the information? I guess I could 
avoid dual edits. etc. by keeping all commands in external sources and 
use make to generate the actual kickstart files, but does anaconda offer 
other options?
