On boot or after I stop/start a jail, I see the following message on the console:
ng_ether_ifnet_arrival_event: can't re-name node XXX where XXX is the name of the jail's network interface. I am using the /usr/share/examples/jails/jng script to create a netgraph(4) VNET interface for the jail but I am unable to find a solution for preventing that message in the first place.
