Updated from Fedora 18 to Schroedingers Cat ( FEdora 19 )

I updated from Fedora 18 to 19 with fedup

fedup --network 19 --reboot 

Updated worked without problems, but the default-boot  didn't succeed to complete.

My /var isn't on a separted lvm partition. After finding out that the default language is now english in the
ASCII-Screens, I could log in and see with journalctl -xb what problems occured.

After mkdir /var/log and a reboot, the system came back online with the Gnome-Login screen.
