What do you suggest? 

I dont know how that behaves in all environments in order to answer that
question and I've following "However, in containers reboot() call is
ignored"[1] in my head since I've discovered it.

What do you suggest? 

Does that additional return hurts that much? I mean, if we keep it, it's
clear, that the code bellow the return cant be ever reached, omitting it
leaves some possibility. Debugging this stuff is PITA.
