*** Bug 1241291 has been marked as a duplicate of this bug. ***

Comment 4 Tomáš Hozza 2015-07-13 15:29:09 UTC
So the issue seems to be that SELinux denies the access to /sys/fs/cgroup/systemd. Please see Bug #1242430

Comment 5 Tomáš Hozza 2015-07-15 13:27:26 UTC
This Should not happen any more on Fedora, since we changed the script to send the NM signal if the NM is new enough. NM is new enough in F22+ so the check that failed will not get executed.
