SYSTEMD: Give us a option for upstart

[Reindl Harald]

PLEASE give us a option for systems upgraded with yum
NOT USING "systemd" and force "upstart" as before

* the system is running since years
* every dist-upgrade via yum was no problem
* now see screenshot
* WTF is there to relabel if started with "selinux=0"-kernel-param

WHY IN THE WORLD ARE USERS FORCED TO USE SYSTEMD ONLY BECAUSE
THEY UPGRAD TO F15? DO THIS FOR NEW INSTALLATIONS BUT NEVER
ON UPDATES

I DO NOT NEED SYSTEMD ON 20 SERVERS HERE BECAUSE THEY ARE STARTING
FAST ENOUGH AND I NEED NO MAGIC WHICH THINKS KNOWS WHAT TO START
IN WHICH ORDER SINCE I KNOW WHAT IS RUNNING ON MY SYSTEMS
