There are two issues here. First, if we're going to keep network_interfaces around, /etc/rc.d/dhclient should honor it and not start dhclient on interfaces not in either network_interfaces or removable interfaces. Second, running ifconfig should not be triggering link events. That makes no sense. I'll have to see if can replicate that, I'm a bit dubious. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
