28# This is the second phase of TCP/IP configuration.  The first part is
29# run by the svc:/network/physical service and includes configuring the
30# interfaces and setting the machine's hostname.  The svc:/network/initial
31# service does all configuration that can be done before name services are
32# started, bar configuring IP routing (this is carried out by the
33# svc:/network/routing-setup service).  The final part, run by the
34# svc:/network/service service,  does all configuration that may require
35# name services.  This includes a final re-configuration of the
36# interfaces.
