  39 # If DHCP was used on a primary interface then set the hostname
  40 # that was returned. If no hostname was returned, set the name
  41 # to be "unknown". The hostname must be set to something, because
  42 # tooltalk will hang unless the name can be locally resolved.
  43 # Sendmail also requires the name to be resolvable locally.
  44 # Later, in inetsvc, we create a name "unknown" and create a entry
  45 # in the local /etc/inet/hosts file pairing "unknown" with the IP
  46 # address assigned by DHCP.  The use of bootparams as a fallback
  47 # for all non-DHCP cases provides compatibility with the
  48 # behavior of the system before netstrategy was introduced.
  49 #
  50 # For non-global zones, fall back to the `uname -n` value provided by the
  51 # kernel if /etc/nodename does not exist, as is expected on an initial boot.
