Perform an Inception. Mount your iso, then mount the image found inside. Go inside the second image to see what is available during the pre install section of a kickstart. Use isomaster to rebuild the install.img and plop that inside the the outer iso, rebuilding that one too.
The pre-install is not inside a chroot environment, so whatever variables you set or export are only available for use outside of a chroot. And that’s the problem with the post install section, by default anyway.
and then I ran across this post with palm and blackberry users whining about their crappy devices, praying for the next gen linux smartphone gods to save them.
