   (that was quoting xterm's manpage)   
      
   fwiw xterm relies upon utempter to do what's appropriate.   
      
   In a quick check, that's since   
      
   Patch #188 - 2004/5/12 - XFree86 4.4.99.6   
      
        * improve  ifdef's  for  utempter  library  to  omit direct calls to   
          setutent() or getutent() (adapted from patch by Christian Biere).   
      
   The README for utempter says   
      
   	The utempter is a privileged helper used by libutempter library to manipulate   
   	utmp and wtmp files.   
      
   and (the documentation appears to be written in C) the last thing utempter   
   does if no errors stop it is this:   
      
   	(void) updwtmp(_PATH_WTMP, &ut);   
      
   utempter uses setgid, while systemd (whose documentation is per-line of   
   code no better than utempter) appears to require root privilege   
   (which of course is a big step backwards).
