49# interfaces that don't modify the per-interface setting with the
50# router or -router ifconfig command in their /etc/hostname.<intf>
51# files.  Due to their dependency on this service, the IP forwarding services
52# will run at this point (though routing daemons will not run until later
53# in the boot process) and set forwarding flags.
