Sure, I use purley python in all my kickstarts, he's an excerpt from the beginning of my "pre" section: %pre --interpreter /usr/bin/python # Begin KickstartConfigMenu.py snippet """ KickstartConfigMenu.py A cobbler snippet to parse user input pre build to later be parsed by a kickstart file during or post.
