- If the dhclient were to receive a DHCPNAK while it was in the RENEW
state (and consequently, had an active, 'bound' address and related
configuration options), it would fail to 'tear down' this information
before proceeding into INIT state. dhclient now iterates the dhclient-
script with the 'EXPIRE' action to cause these teardowns prior to entering
INIT state. [ISC-Bugs #16035]
