51# interfaces that don't modify the per-interface setting with the
52# router or -router ifconfig command in their /etc/hostname.<intf>
53# files.  The -F option tells routeadm to only update the forwarding
54# configuration for the system, and not dynamic routing.  We don't
55# want routing daemons started until later in the boot process (see
56# the net-init method for that).
