   3 Subject: alfred: Show error message for invalid batadv interface
   4
   5 The alfred server process always stopped without any informational message
   6 when the provided batman-adv was not "none" and was not accessible. This
   7 made it extremely hard to debug the reason why alfred directly stopped
   8 after launching it.
