RHEL7 - Kickstarting from Satellite

Efforts to kickstart a RHEL7 install from my 5.4.1 Satellite are proving fruitless.

Current issue is that the Satellite generated kickstart doesn't put %end at the end of the %packages section. Is my Satellite up to the task? (I know there are a few upgrades outstanding).

Anybody managed to get RHEL7 deployed from Satellite kickstart?
