Hi Ansgar,

thanks for testing the v246 package from experimental.

Looks like something we should file individual bug reports for or add a
lintian check. I decided for the latter for now.

Dear lintian maintainers, please see
https://github.com/systemd/systemd/blob/master/NEWS#L101

```
* StandardError= and StandardOutput= in unit files no longer support
  the "syslog" and "syslog-console" switches. They were long removed
  from the documentation, but will now result in warnings when used,
  and be converted to "journal" and "journal+console" automatically.
```

Since journal is the default anyway, I guess the best recommendation is,
that maintainers simply remove any such lines from their unit files.

Interesting, I've not seen this one before. Might be worth investigating
separately what this is about if it's reproducible.

Hm, this appears to be https://github.com/systemd/systemd/issues/16319

I appears the offending two commits were (unfortunately) cherry-picked
into v245.6 and fixed in v246. Since this is supposedly a transient
issue and upgrades from buster should not be affected, I'm inclined to
close this bug report. WDYT?
