If you have a Red Hat Satellite Server or Spacewalk Server, you can create bootable ISOs from the Kickstartable Trees.
Log in via SSH to your Red Hat Satellite Server or Spacewalk Server.
Change into the Kickstartable Tree root directory:
cd /var/satellite/rhn/kickstart/
Change into the Kickstartable Tree directory you want to create a bootable ISO of (I will be using RHEL 6.4 64-bit in this example):
cd ks-rhel-x86_64-server-6-6.4
Run the following command to create the bootable ISO:
mkisofs -o /tmp/rhel-x86_64-server-6-6.4.iso -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R -J -v -T .
The final ISO will be stored at /tmp/rhel-x86_64-server-6-6.4.iso.
