Description Phil Wyett 2016-11-23 22:40:04 UTC
Description of problem:

SELinux is preventing /usr/libexec/colord from read access on the file /etc/udev/hwdb.bin.

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

If you believe that colord should be allowed read access on the hwdb.bin file 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:
# ausearch -c 'colord' --raw | audit2allow -M my-colord
# semodule -i my-colord.pp
