You're sure this isn't going to f--k my perfectly running system (yes, I do 
have f13 installed on a different partition, but I would not be happy with that 
and would want at least f14, if rawhide screws up).

So...

I install the fedora-release-rawhide package from rawhide and then yum update, 
and I guess I would manually have to reinstall systemd-sysvinit, too, right?
