Hence the notion of a neteventd -- I don't really mind what container it's in, as long as its structured around the network-centric pieces. > It's really a lot easier the process a small list of events in dhacpd as > a result of a kqueue or kqueue/select combo, if you want to avoid > rewriting as much code as humanly possible, and still be able to pull > this feature out of the project. Absolutely agreed. If OMAPI is working well, that may well provide a lot of what we want. One benefit to central management of the network configuration would be that we'd get things like GUI control and profiles a lot more easily. > I still haven't been able to repeat your test; are you sure you are > listening on a routing socket for the configuration change events? > Maybe I'm doing something silly with my dumb little test program that > you aren't doing with yours?

I've tested two different situations with "route monitor" creation and removal of virtual interfaces (in this case, vlan interfaces), and physical interfaces (in this case, my wi0 card in my notebook). Both appear to be generating proper notifications during arrival and departure. The only events that I expected to see, but didn't, were IPv6 link layer address arrival and departure. I ran these tests with 5.0-CURRENT from around July 3, but I seem to recall seeing this work properly previously. I don't have any RELENG_4 boxes with removable physical interfaces at this point.
