I am trying to edit the original RHEL 6.5 DVD (rhel-server-6.5-x86_64-dvd.iso) from redhat in order to add kickstart file on it. The goal is to have one 3.4Go iso with automatic install. And not one boot media and one DVD.This technique is not supported by redhat officially, but I found a procedure : https://access.redhat.com/solutions/60959My ks.cfg looks like :installcdromrepo --name=Red Hat Enterprise Linux  --baseurl=file:/mnt/source --cost=100repo --name=HighAvailability --baseurl=file:///mnt/source/HighAvailabilityI got an error when the installer start : it didn't find the disk Red Hat Enterprise Linux.I guess this is because installer is not looking on its own media. Is there a way to achieve this ? Does the cdrom have optional parameter to hard link the device ?
