            the state at least for 96 hours (Update in Progress has an
            additional upper limit of 144 hours).

            In order to fulfill the above requirement, even if the node might
            be powered off once in a while, we need to store persistently
            how many hours the node has been in the state. This doesn't
            necessarily need to happen every hour (thanks to the flexible
            duration range). The exact cadence will depend a lot on the
            ways that the node will be used and what kind of power source it
            has.

            Since there is no single optimal answer, this configuration
            option allows specifying a divider, i.e. how many intervals
            the 96 hour minimum gets split into. After each interval the
            duration that the node has been in the current state gets
            stored to flash. E.g. the default value of 4 means that the

            This value affects memory and call stack consumption, which
            is why the default is lower than the maximum that the
