                <para><filename>systemd-user-sessions.service</filename>
                is a service that controls user logins. 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>
