Description Lukas Slebodnik 2018-06-28 08:16:14 UTC
SELinux is preventing /usr/sbin/load_policy from map access on the file /usr/sbin/load_policy.

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

If you believe that load_policy should be allowed map access on the load_policy file 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 'load_policy' --raw | audit2allow -M my-loadpolicy
# semodule -i my-loadpolicy.pp
