When building a new RHEL v7.8 VM manually, I set up the rules desired in /etc/audit/rulesd/audit.rules, no other changes (because I've wanted to narrow down the issue). After subsequent reboots, with no further changes to any audit rules either; I monitor /var/log/messages and I see occurrences like this:

The 'usage' of auditctl is invoked the one time in the 'try_load' function of augenrules.  Manual executions of "/sbin/auditctl -R /etc/audit/audit.rules', results in essentially the same behavior on the terminal as found in /var/log/messages.
Should execution of augenrules seemingly error-out on invocation of auditctl like this?
Thank you.
