After basic system initialization is complete it removes <filename>/run/nologin</filename>, thus permitting logins. Before system shutdown it creates <filename>/run/nologin</filename>, thus prohibiting further logins. At the same time it also kills all user processes, so that system shutdown may proceed without any remaining user processes around.</para> </refsect1> <refsect1> <title>See Also</title> <para> <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>, <citerefentry><refentrytitle>systemd-logind.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>, <citerefentry><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry> </para> </refsect1> </refentry>
