Hi,
looking at the commits related to conntrackd, this behaviour seems to be somewhat intended.
Not being involved with this, my guess conntrackd is required for special setups, and there is no need for this daemon to run on an “ordinary” IPFire installation (personally, I cannot recall to be ever in need of it).
However, the entire thing is rather sketchy, perhaps @ms can elaborate a bit more on it so a proper documentation can be added.
This sounds like this file was present before upgrading to C161. Is this true or did I misunderstood you?
Thanks, and best regards,
Peter Müller
