I am getting a similar, possibly related error:
SELinux is preventing mkdir from create access on the directory chrony-dhcp.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that mkdir should be allowed create access on the chrony-dhcp 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 'mkdir' --raw | audit2allow -M my-mkdir
# semodule -X 300 -i my-mkdir.pp
