117  halt
118
119    This is a program which gets run by zoneadmd when a zone is being
120    halted.  This callback is provided to allow a brand to cleanup any
121    special configuration that was setup during boot.
122
123    This program will also be invoked by zoneadmd if any part of the zone
124    booting process fail, even if the booting process failed before the
125    brand boot program was invoked.  It is also possible that if the zone
126    fails to halt after invoking this program, future attempts to halt the
127    zone will invoke this program again.  So this program should be
128    designed to clean up any resources allocated to a zone but it should
129    also be able to gracefully handle the case where resources that it
130    expects to release are not actually allocated (or have been already
