* Recreate Supervisor container on OS upgrade/downgrade When the operating system gets upgraded or downgraded the Supervisor start script might start the Supervisor slightly differently (e.g. with RT scheduling support). If the container has already been created, a OS upgrade or downgrade won't recreate the Supervisor container. * Move startup script version file to /mnt/data
