Description Charles R. Anderson 2015-01-29 13:49:53 UTC 
Description of problem:
SELinux is preventing dnssec-trigger- from 'read' accesses on the directory /var/tmp.

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

If you believe that dnssec-trigger- should be allowed read access on the tmp directory 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 dnssec-trigger- /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Charles R. Anderson 2015-01-29 14:16:54 UTC 
I think this was caused during a "dnf update" while the system was running. dnssec-triger and systemd were bot updated.  dnssec-trigger also crashed during this time.
