I tried that indeed, buf for some reason, some devices stay busy after
being used (eg if tinc crashes, cf my other report).
I have not investigated this a great length (could be a freebsd bug
instead perhaps) but I found it usefull that tinc could try to find an
inetrface on its own, just like it does on Linux for instance.
(eg, this allows one to run several instances of tinc without specific
configuration).
I can understand however that it might not be wanted on setups where
tinc has to bind to a very specific interface, so maybe there needs to
be a way to turn it on or off ?
