  56
  57     <para><filename>systemd-user-sessions.service</filename> is a
  58     service that controls user logins. After basic system
  59     initialization is complete it removes
  60     <filename>/run/nologin</filename>, thus permitting logins. Before
  61     system shutdown it creates <filename>/run/nologin</filename>, thus
  62     prohibiting further logins. At the same time it also kills all
  63     user processes, so that system shutdown may proceed without any
  64     remaining user processes around.</para>
