Description Ensley Feemster 2011-02-04 15:03:10 UTC
SELinux is preventing /lib/upstart/shutdown from 'ioctl' accesses on the file /var/log/lxdm.log.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that shutdown should be allowed ioctl access on the lxdm.log file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep shutdown /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
