I'm still seeing this with 41.20.

SELinux is preventing daemon-init from watch access on the directory /etc/mdevctl.d.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow daemon-init to have watch access on the mdevctl.d directory
Then you need to change the label on /etc/mdevctl.d
Do
# semanage fcontext -a -t FILE_TYPE '/etc/mdevctl.d'
where FILE_TYPE is one of the following: mdevctl_conf_t, virt_cache_t, virt_common_var_run_t, virt_etc_rw_t, virt_var_run_t, virtnodedevd_t, virtnodedevd_var_run_t.
Then execute:
restorecon -v '/etc/mdevctl.d'


*****  Plugin catchall (17.1 confidence) suggests   **************************

If you believe that daemon-init should be allowed watch access on the mdevctl.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:
# ausearch -c 'daemon-init' --raw | audit2allow -M my-daemoninit
# semodule -X 300 -i my-daemoninit.pp

I believe v41.22 build addresses the issue with /etc/mdevctl.d label.
