/* _doPowerEmergencyShutdown()
*
Performs a semi-complicated proecdure to get machines experiencing power failure
to automatically power up when external power is restored. We do this to trigger
the onboard "Restart Automatically after a power failure" feature; pulling the power
from a mostly-shutdown machine simulates a "power failure."
At the time we do the shutdown...
The UPS has lost external power (presumably due to a power outage) and our backup
power thresholds have been exceeded and we've decided to do a system shutdown.
1. Request that the UPS remove power from the system in kDelayedRemovePowerMinutes
2. Set the StallSystemAtHalt root domain property that will cause the machine to hang
at shutdown (after the OS has been shutdown).
3. We run the emergency shutdown script (/usr/libexec/upsshutdown) and shutdown to
the point of stalling.
4. OS hangs there at the endpoint, waiting for UPS to remove power to its AC plugs.
Later...
1. External power is restored to the UPS
2. The UPS restores power to its outlets, the CPU's "Restart Automatically after a
power failure" switch is triggered. System boots up and resumes operation.
