I really like Rod's idea better. By putting:
network_interfaces="`ifconfig -l`"
^^^^
note: that should be /sbin/ifconfig, because
/sbin may not be in the path in all cases.
Into /etc/defaults/rc.conf we would maintain virtually complete
backwards compatibility while getting the same result. It is the
most painless way to make this change, and people can still
override it in /etc/rc.conf. This is a whole lot better then
making a change that ignores the network_interface variable.

:I don't think that would be much better. I've shown you how to make
:the current (before your commit) system do what you want, and still do
:what I want. What more do you need?
