The auto-revert reboot count tolerance, used in conjunction with the
value of juniSystemBootAutoRevertTimeTolerance when
juniSystemBootAutoRevertControl is set to set(2) in the same PDU. For
example, if this object is set to 4 and
juniSystemBootAutoRevertTimeTolerance is set to 1200, then the boot
logic will choose backup mode if 4 system reboots occur within 20
minutes. This object cannot be set to zero, but may contain a zero
value when juniSystemBootAutoRevertControl is set to never(1).
