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