Description Adam Williamson 2013-06-25 14:25:31 EDT
Description of problem:
Left a VM with an F19 Final RC1 test install running for a while, came back to it to shut it down to test something else and this alert was showing.
SELinux is preventing /usr/lib/polkit-1/polkitd from using the 'signal' accesses on a process.

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

If you believe that polkitd should be allowed signal access on processes labeled policykit_auth_t 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 polkitd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
