# * any other MAC address
#
# If none of the above could be found, default to "headnode" for headnodes, and

# Sendmail also requires the name to be resolvable locally.
# Later, in inetsvc, we create a name "unknown" and create a entry
# in the local /etc/inet/hosts file pairing "unknown" with the IP
# address assigned by DHCP. The use of bootparams as a fallback
# for all non-DHCP cases provides compatibility with the
# behavior of the system before netstrategy was introduced.

# For non-global zones, fall back to the `uname -n` value provided by the
# kernel if /etc/nodename does not exist, as is expected on an initial boot.
