Yes, but if interface had _never_ received any pfsync packet,
and sysctl is set to net.inet.carp.preempt=0 ?
Maybe it's because of that. Don't know really. Documentation for
this is not so good. Someone who knows this code and how this really
works, should write handbook like documentation. Clusters are
always complex, and for that, docs should be *very* detailed.
If someone does that, I'll buy him a beer.
