Without implementing a complex system such as the node state manager from Genivi, will still need to provide a solution such as:

 when stopping the system we need to store the application that will need to be autorestarted at reboot, in which order and which one shall be displayed.

e.g on reboot start and display navigation and play last radio station in background.

See use case and presentation.
