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.
