Ok, state.settings.syslog is 0 and state.settings.syslog_only = false
when we enter reopen_logs() before lp_loaded() returns true.

So the initial message (with loglevel >= 0, which means all) only went
to the log file and not to the syslog.

Can you file a bug report and add the url to the commit messages
and also push it through a gitlab pipeline?
