I'm trying to create a bootable DVD with RHEL4u5 and my kickstart
script
to perform an unattended install.

My image boots and sees the ks.cfg file just fine. However, it quickly
says:

The Red Hat Enterprise Linux CD was not found in any of your CDROM
drives. Please insert the Red Hat Enterprise Linux CD and press OK to
retry.

Googling gives me a bunch of responses that say "You didn't copy the
.discinfo file". But I did! And it's contents are identical to a
working
image:

1177148299.639333
Red Hat Enterprise Linux 4
i386
1,2,3,4,5
RedHat/base
RedHat/RPMS
RedHat/pixmaps

Use CentOS: they were much better about providing bootable DVD's, and kept
their DVD building tools up-to-date. (I rewrote their tool for the weird
layout of RHEL 5 and sent both RedHat and CentOS the modifications.)
