Szerintem nem jó file-t importáltál. Fedora 19 esetén ezt írja a könyv:
rpm --import https://fedoraproject.org/static/FB4B18E6.txt
Másrészt ezt találtam:
Incompatible systemd cgroups hierarchy layout
systemd in F19 lays out its cgroups hierarchy differently than in previous Fedora releases.
The new hierarchy has some advantages, but it is incompatible with the old one. No live conversion of the hierarchy is performed during the package upgrade, so the upgraded systemd will not understand the previous state of the system correctly. This is known to affect the tracking of user sessions by systemd-logind (bug #962983).
Expect breakage in active user sessions and make sure to reboot soon after performing the upgrade. If your screen locks during the upgrade, you may not be able to log back in due to the cgroup changes. Running the upgrade in a screen(1) session has been reported as a workaround (re-attach from a vt).
