Comment:
Seems like the solution is to discard `stdout` where metalog prints every log line it receives https://github.com/hvisage/metalog/blob/bb7c007cbc0815fd08e9259b26dcef26020217d0/src/metalog.c#L1412.

And to keep the error messges from `err(3)`, either keep stderr open and leave it there so the error messages end up in the fallback mechanism, or redirect them to stdout which makes them end up in `/dev/console` without having a log service.

```
#!/bin/sh
[ -r conf ] && . ./conf
exec metalog ${OPTS} >/dev/null
```
