Description of problem:
SELinux is preventing systemd from using the 'mac_admin' capabilities.

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

If you believe that systemd should have the mac_admin capability 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 'systemd' --raw | audit2allow -M my-systemd
# semodule -X 300 -i my-systemd.pp
