Some of the devices have the concept of a running and a startup configuration. The running configuration is what gets created/updated at runtime and would be dependant on what the Device Manager or VOLTHA asks the device to do. For these type of devices, every time the device boots up, it overrides it's running configuration with the startup configuration.
The API UpdateStartupConfiguration can be used to modify this startup configuration of the devices. Most of the standard running configuration would come from VOLTHA or the Device Manager, but there could/would be some properitary configuration that the devices need and this can be modified using this API.

+The below diagram shows the FSM state transitions for the device image management.

Note: The on-demand metrics query using the API `GetMetric` would be passed back over GRPC and not over the kafka bus.
-The device shall not locally persist the events across the reboot. The NEM implementations are expected to purge all the unresolved events (events for which the corresponding RECOVERED events have not yet been sent) on the device reboot, as the device shall detect and report the events afresh after the reboot.
+The device/device manager implementations shall persist the active events across the device reboot. On the device reboot, the alarms which are no longer active shall be cleared.
