32# it tries to do is irrelevant (and will actually lead to the service
33# failing if we try to do it), so just bail out.

40# configured.  This is not strictly necessary but makes it so that in.mpathd
41# will always be started explicitly from /lib/svc/method/net-init (the
42# svc:/network/initial service), when we're sure that /usr is mounted.

47# Before any interfaces are configured, we need to set the system
48# default IP forwarding behavior.  This will be the setting for
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.
