The perl script I posted takes all the CD-ISO images, mounts them and
then merges them into a single installable DVD image. All the RPMS are
under a single RPM directory, the DVD is bootable and the installation
tools see the DVD as a single unified RedHat install disc, not 6
seperate images. I think it does exactly what you are asking for, no?
A big DVD install disc vs. a bunch of single CDs.
Here's the script again for reference:
#!/usr/bin/perl
#
# This is a perl util to make a DVD from RedHat 9 iso CD discs
#
# Howto:
# 1st: You'll need about 7.5GB if free space.
# 2nd: You'll need root permissions so mkisofs can mount and umount
#
# 1) Download the RH9 ISOs from /pub/redhat/linux/9/en/iso/i386
# 2) Place them all in a directory with this script
# 3) chmod +x ./make_disc
# 4) sudo ./make_disc
# 5) You'll have a DVD iso image that can be burned using your fav.
