The system boot auto-revert control is used to determine when the boot
logic should choose backup mode based of the reboot history:
default - Use the default auto-revert tolerances: 3 reboots in 30
minutes.
never - Never auto-revert to backup mode.
set - Use the auto-revert tolerances specified by
juniSystemBootAutoRevertCountTolerance and
juniSystemBootAutoRevertTimeTolerance, which must be
specified in the same PDU as this object when this value
is specified.
