I would however like to kickstart new servers based on RHEL 5.7. Both official Red Hat channels in Satellite are already updated to RHEL 5.9 and RHEL 6.4 though.
Red Hat Enterprise Linux (v. 5 for 64-bit x86_64) Red Hat Enterprise Linux Server (v. 6 for 64-bit x86_64)
Can I create a frozen RHEL 5.7 channel based on the official Red Hat Channel that is already updated to the latest RHEL 5.9 on the Satellite server?
If not, how can I create a kickstartable RHEL 5.7 channel?
