With just 'force autoconf { fritz.box }' as config:
$ unwindctl status
1. recursor validating, 70ms 3. autoconf dead,
N/A
2. oDoT-autoconf dead, N/A 4. stub dead,
N/A
Adding 'preference { autoconf }' doesn't change it from dead, but
resolving the forced name will work, still.
1. autoconf dead, 15ms

Here's the daemon log from startup over a few seconds of wait to
'host fritz.box. ::1' timing out.
