So on the first attempt, auditd only got so far in its initialization
before exiting and thus didn't generate the later set of audit messages.
You can keep interatively generating new policy modules as you did above
and inserting them until you get a working auditd, or you can just
switch to permissive mode temporarily (setenforce 0), start auditd to
generate the full set of audit messages, and generate the final policy
module in one go. Then switch back to enforcing mode (setenforce 1).
A finer-grained way of doing this is coming via permissive domains,
where you can make a single domain permissive.
