application:start(MyApp, permanent).

Another way, I think, - add dummy child to your supervisor tree, which could
call

init:reboot()

on shutdown message, as could do `terminate' callback in 'gen_*':

terminate(shutdown, State) ->
  init:reboot();
terminate(Other, State) ->
  ok.

Child spec in supervisor mustn't be `brutal_kill' for this to work.

Best Regards,
