<title>Description</title>
<para>The <command>systemd-mute-console</command> tool and service may be used to
temporarily mute the log output of the kernel as well as the status output of the service manager to
the system console. It may be used by tools running on the console to ensure their terminal output is not
interrupted by unrelated messages.</para>
<para>The tool can be invoked directly in which case it will mute the two outputs and then issue an
<citerefentry><refentrytitle>sd_notify</refentrytitle><manvolnum>3</manvolnum></citerefentry>
<literal>READY=1</literal> notification once that is completed. On <constant>SIGINT</constant> or
<constant>SIGTERM</constant> output is unmuted again. Alternatively it can be invoked via Varlink
IPC.</para>
