009.04.91.34. Could you walk us through the process of how the `08_fallback_counting` script handles

PROCESS OF FUNCTIONING OF FALLBACK BEHAVIOUR BY `FALLBACK_COUNTING` SCRIPT -

Two environment variables `boot_counter` and `boot_success` are used for above process.


CHECKING BOOT COUNTER AND BOOT SUCCESS -
if[ -n "${boot_counter}" -a "${boot_success}"="0" ]
then
    #..( further logic here )
fi

--It checks if `boot_counter` variable is set ( if boot tracking system is in place) and if `boot_success` variable is set to "0" ( boot failure )
{ fallback behaviour code in semantics  as described below... }

If `boot_counter` has reached "0" or "-1", the fallback behavour code sets the default boot entry to "1".
If `boot_counter` is greater than "0", it decrements the counter by one using the `decrement` command which comes from `increment` module.
This variable is saved using `save_env` command.
