Description steinach2810 2013-12-16 12:48:01 UTC
Description of problem:
trying to start sensord.service with ExecStart = /usr/sbin/sensord -i $INTERVAL -l $LOG_INTERVAL --rrd-file /var/log/sensord.rrd

the Round Robin Database, which should keep the sensord daemon's (/var/log/sensord.rrd) was not allowed to be created by the daemon after running "sudo service sensord start", when it should.

systemctl status sensord.service:

sensord.service - Sensor Information Logging
   Loaded: loaded (/usr/lib/systemd/system/sensord.service; disabled)
   Active: failed (Result: exit-code) since Mon 2013-12-16 14:42:01 EET; 4min 43s ago

SELinux is preventing /usr/sbin/sensord from 'write' accesses on the directory /var/log.

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

If you believe that sensord should be allowed write access on the log 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 sensord /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
