One used the POWER sig to > trigger the shutdown script. z/VM 4.3 has the SIGNAL SHUTDOWN command that can be used with Linux. (I think Neale wrote some Linux code to intercept the signal.) This is the same mechanism that z/VM 4.3 itself will use if the LPAR is deactivated to issue its own CP SHUTDOWN.
