  31
  32     <para><filename>systemd-user-sessions.service</filename> is a
  33     service that controls user logins through
  34     <citerefentry project='man-pages'><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
  35     After basic system initialization is complete, it removes
  36     <filename>/run/nologin</filename>, thus permitting logins. Before
  37     system shutdown, it creates <filename>/run/nologin</filename>, thus
  38     prohibiting further logins.</para>
