Controlling interface availability, was Re: "bridge0 is not a bridge"?

["Michael R. Jinks" <mjinks_(_at_)_saecos_(_dot_)_com>]

Hi, all.  Still trying to make bridging work.  After a little comparison 
with another OBSD machine, I now realize that this unit doesn't appear 
to have bridging configured at all; ifconfig -a does not return any 
bridge interfaces.

I didn't build this box's OS image.  It was pre-installed by the fine 
folks at SeraSystems, and I'm wondering if maybe their kernel config (or 
something?  what else could it be?) left out bridging, but I don't know 
how to verify that.

I regret my newbieism in this regard.  Have sent mail to SeraSystems, 
I'm sure they'll get back to me, but in the meantime I'd like to know 
how to look for myself.

/usr/src/sys/conf/GENERIC has bridging switched on, but I doubt that the 
standing kernel was actually compiled on this unit so that's probably 
irrelevant.

/kern doesn't show anything that's obvious (to me), but I don't know 
where to look.

Hints?

Thanks...
