:SELinux is preventing /usr/bin/systemctl from 'getattr' accesses on the file /run/log/journal/57f7afd2e1764d6796dc9f746850af63/system.journal.
:*****  Plugin catchall (100. confidence) suggests  ***************************
:If you believe that systemctl should be allowed getattr access on the system.journal file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep systemctl /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Adam Williamson 2012-04-04 03:16:05 UTC
I seem to hit four of these, consistently (as well as this 'getattr', there's a 'read' on 'system.journal', a 'read' on 'journal', and a 'search' on 'log') if I do a default live install of F17 Beta RC3-ish (a test live image I built with GNOME 3.4 and the new selinux-policy), do 'systemctl disable NetworkManager.service' then 'systemctl stop NetworkManager.service' to stop NM, edit /etc/sysconfig/network-scripts/ifcfg-eth0 to set NM_CONTROLLED=no and ONBOOT=yes , and do 'systemctl start network.service'. 

The systemctl start operation never completes. If I boot with enforcing=0, it completes quickly.

Comment 2 Miroslav Grepl 2012-04-04 06:37:24 UTC
Well not sure why it should fail because of this. CC-ing systemd folks. I need to test it too.

Comment 3 Michal Schmidt 2012-04-04 07:10:52 UTC
The denial seems to be just another case of bug 794771. But it does not explain Adam's observed hang of 'systemctl start network.service'.

Adam, what does 'systemctl status network.service' show while the start operation is hung?
