RHEL5 kickstart needs to mount cdrom in postinst

[Shabazian, Chip]

I'm not sure how much you need available from the cdrom in the %post,
but I used a workaround in the past when I wanted to get information
from %pre to %post which might help.

What I did was create a ramdrive in %pre and copy what I needed to it.
As long as you umount the ram drive, you can then mount it in %post and
access everything.

As long as what you need in your %post is small enough to fit on a ram
drive, you can use this as a workaround.

You are correct; the problem is that the CD gets ejected before the post
install script executes. This is different as compared to the behavior
of RHEL4.

Not knowing what the rational was to change this, I can only conclude
that this is a major problem for us. We use Kickstart to custom install
an application on an appliance style product using a slightly modified
RHEL5 install CD and we need to be able to add a couple files during
post install from the CD.

Is there a way to patch Anaconda to get it to not eject the CD?  Where
should I start looking?
