Double addition of rule yields two log messages

Its true that my auditd.conf (which I don't think I've ever
modified) has freq = 20 and flush = SYNC.  I assume that SYNC
means that freq is ignored.  The manpage says freq is only valid
if flush=incremental so it seems like an unnecessary warning.

But why does ausearch care?  Seems like if anything cared it
would be the auditd but I can't find an error or warning from
it anywhere.  Seems really odd that this message comes from
ausearch.
