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