That looks fine to me.

No, that should work fine and the stub should be used once configured. 
All I can think of is that some people report that on FreeBSD there is
at some times confusion and they edit the wrong unbound.conf file, their
edits are ignored because a different config file is used by unbound. 
(I think because there are separate configs for different instances;
also Debian has an alternatives mechanism that puts the files in some
other location or was that Ubuntu).

Set verbosity: 4 and see what goes wrong here.  At startup it should
straight away log the stubs and forwards that it read in.

Best regards, Wouter
