Introduction

As of this writing, the current RHEL release (5) is only available on CDs, not DVD. It is possible to create a bootable DVD ISO from these CDs using Chris Kloiber’s mkdvdiso.sh script.

Method 1

Script mkdvdiso.sh

Insert this in a mkdvdiso.sh file:

# A quick hack that will create a bootable DVD iso of a Red Hat Linux
# Distribution. Feed it either a directory containing the downloaded
# iso files of a distribution, or point it at a directory containing
# the "RedHat", "isolinux", and "images" directories.
 
# This version only works with "isolinux" based Red Hat Linux versions.
 
# Lots of disk space required to work, 3X the distribution size at least.
 
# GPL version 2 applies. No warranties, yadda, yadda. Have fun.
 
 
if [ $# -lt 2 ]; then
	echo "Usage: `basename $0` source /destination/DVD.iso"
	echo ""
	echo "        The 'source' can be either a directory containing a single"
	echo "        set of isos, or an exploded tree like an ftp site."

fi
 
rm -rf $DVD/isolinux/boot.cat
find $DVD -name TRANS.TBL | xargs rm -f
 
cd $DVD
mkisofs -J -R -v -T -o $2 -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table .
/usr/lib/anaconda-runtime/implantisomd5 --force $2
 
cleanup
echo ""
echo "Process Complete!"
echo ""

Install the anaconda-runtime

Prerequisite package and its dependencies:

1

yum -y install anaconda-run || timerpm -q anaconda-runtime

Make DVD

Place the CD ISO files and mkdvdiso.sh in a directory, and run the mkdvdiso.sh script.

1

chmod 755 ./mkdvdiso.sh && ./mkdvdiso.sh

The following command creates a RHEL bootable DVD ISO:

1

./mkdvdiso.sh . $(pwd)/RedHat-dvd.iso

The file .discinfo should look like:

1170972069.396645
Red Hat Enterprise Linux Server 5
i386
1,2,3,4,5
Server/base
Server/RPMS
Server/pixmaps

Method 2

Create folders:

1

mkdir /mnt/cd{1,2,3,4,5}

Mount every iso image with:

1

mount -o loop cd1.iso /mnt/cd1

Copy the minimum:

1

cp -a cd1/isolinux cd1/.discinfo .

Edit the .discinfo and replace 1 with:

1,2,3,4,5

Do this for all your CDs. Then:

1
2
3

mkisofs -o redhat.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -m TRANS.TBL -x \
/mnt/cd1/.discinfo -x /mnt/cd1/isolinux -graft-points /mnt/cd1 .discinfo=.discinfo isolinux/=isolinux RedHat/=/mnt/cd2/RedHat RedHat/=/mnt/cd3/RedHat \
RedHat/=/mnt/cd4/RedHat RedHat/=/mnt/cd5/RedHat

Adapt this for your specific needs.
