  57     <title>Description</title>
  58
  59     <para><filename>systemd-user-sessions.service</filename> is a
  60     service that controls user logins through
  61     <citerefentry project='man-pages'><refentrytitle>pam_nologin</refentrytitle><manvolnum>8</manvolnum></citerefentry>.
  62     After basic system initialization is complete, it removes
  63     <filename>/run/nologin</filename>, thus permitting logins. Before
  64     system shutdown, it creates <filename>/run/nologin</filename>, thus
  65     prohibiting further logins.</para>
