"The system management entries control power management for
the entire system. They are distinguished by the use of the
special device names listed below.
Note that the following _autoshutdown_ entry is not intended
to be hand edited, but to be maintained by the dtpower utility.
If the device_name field contains the special device name
_autoshutdown_, the threshold value specifies the system idle
time (measured as discussed below) before the system may be
shut down by powerd(1M)."
