    <title>Description</title>

    <para><filename>systemd-user-sessions.service</filename> is a
    service that controls user logins through
    <citerefentry project='man-pages'><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
    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.</para>
