Ohh.. and for an example of what does not exist in an ifconfig -l that
gets created later during a /etc/start_if.X you would need something
like ETInc's network cards. eth0 will exist during boot, but eth16
won't until you load the frame layer and map a dlci.
If you at your site want this idea it is a simple matter of setting
network_interfaces=`ifconfig -l` in /etc/rc.conf, but please don't
implement your policy in a way that breaks others operational systems.
