Is there a daemon running as initrc? ps -eZ |grep initrc
It looks like the motion daemon (from RPMFusion) is running as initrc: system_u:system_r:initrc_t:s0 1292 ? 03:25:29 motion It would be accessing the camera device the denial error referenced. Maybe it is responsible somehow? Motion is started by a SysV init script, I don't see anything special in there to set its SELinux context.
Looks like we will need to add motion policy.
I added a policy for motion to fedora17
