Jun 20 18:12:01 Turris_JB syslog-ng[1988]: WARNING: Configuration file format is
too old, syslog-ng is running in compatibility mode. Please update it to use the
syslog-ng 4.2 format at your time of convenience. To upgrade the configuration, please review the
warnings about incompatible changes printed by syslog-ng, and once completed change the
@version header at the top of the configuration file; config-version='4.1'
It’s easy, if you are curious how to get rid of this harmless warning, which will be fixed in upcoming Turris OS version, then:
You need to right now, manually edit the configuration file of syslog-ng, which is located at /etc/syslog-ng.conf and bump the version from 4.1 to 4.2. That’s it.
Syslog-ng is running all the time even though the version was not increased, thus it does not have any impact, but I see that for someone, the warning could be nasty one.
