that this only applies to log messages that are processed by the logging subsystem, i.e. by
<filename>systemd-journald.service</filename>. This means, if you connect a service's stderr directly
to a file via <varname>StandardOutput=file:…</varname> or a similar setting the rate limiting will
not be applied to messages written that way (but they will be enforced for messages generated via
<function>syslog()</function> or similar).</para></listitem>
