  44     <title>Description</title>
  45
  46     <para><filename>systemd-user-sessions.service</filename> is a
  47     service that controls user logins through
  48     <citerefentry project='man-pages'><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
  49     After basic system initialization is complete, it removes
  50     <filename>/run/nologin</filename>, thus permitting logins. Before
  51     system shutdown, it creates <filename>/run/nologin</filename>, thus
  52     prohibiting further logins.</para>
