Description Sayak Sarkar 2013-12-19 13:16:30 UTC
Description of problem:
SELinux is preventing /usr/bin/kmod from 'read' accesses on the directory /etc/modprobe.d.

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

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