If I knew a way to query the state, believe me, I would use it. I
totally understand this seems "ugly" the way it is and I agree 100%.

However, having a master/slave RA is what the cluster needs imho to
fully support conntrackd. Encouraging people to start conntrackd by init
and then have the RA just execute commands for state-shipping seemed and
seems odd to me (that's what the first RA did).

Sure I won't. Maybe a newer version (if exists) includes this. I'll have
another look.
