To be honest, I'm not entirely sure what we're seeing. I run some tests today 
on my system. It's seeing issues also. I'd still like to treat the root cause 
of this. But we do need to change the default. That I what I'm trying to 
figure out.

Back to your question, I'm wondering if we should do both? A changeable 
default in auditd.conf and an override on the command line.
