Damn, really?

Now this is a perfect example of the list working. I didn't know this,
and I found nothing about this in my kickstart manuals. I was limiting
all my post install changes to what I could do from within the kickstart
file itself, and what tools were limited via the booted cd. And for some
reason, I thought the post install interpreter also worked only from the
cd environment, not chroot'ed into my installed environment.
Possibilities do abound, and now my mind is wobbling.  Now someone
giving an in-depth class on kickstart, that I would go to. I never saw
the need for taking the high dollar RHCE classes for my needs, and I
figured those would always be 'how to pass the test' anyway.

I think I'll save rewriting them as a holiday break exercise. Its pre
xmas week and I need eggnog.

Thanks,
