Description Stephen Gallagher 2017-02-27 21:42:07 UTC 
Description of problem:
SELinux is preventing /usr/lib/systemd/systemd from 'mounton' accesses on the directory /usr/lib/modules.

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

If you believe that systemd should be allowed mounton access on the modules 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:
# ausearch -c '(fwupd)' --raw | audit2allow -M my-fwupd
# semodule -X 300 -i my-fwupd.pp
