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.
