From: Sven Eckelmann Date: Mon, 15 Feb 2021 19:56:22 +0100 Subject: alfred: Show error message for invalid batadv interface The alfred server process always stopped without any informational message when the provided batman-adv was not "none" and was not accessible. This made it extremely hard to debug the reason why alfred directly stopped after launching it.
