Bug#1125461: luanti-server: Syslog is flooded with in-game actions

[Christian Weiske]

Package: luanti-server
Version: 5.10.0+dfsg-5
Severity: normal

Dear Maintainer,

When watching the luanti server logs with
> journalctl -efu luanti-server
I see in-game actions like
> ACTION[Server]: username moves stuff to chest at (153,9,173)

These lines appear thousand times per minute and clog the
server logs.

It is possible to put
> debug_log_level = warning
into /etc/luanti/default.conf, but that only affects the lines
logged into /var/log/luanti/default/server.log
- but the actions are still logged into syslog.

The reason is that luanti-server also writes the actions to stdout/stderr,
which gets sent to syslog.

Please find a way to keep the sysylog clean of user actions on the server.
