   Yes, it needs at least 50 characters (and maybe 46+ for IPv6 that includes
   IPv4 at end).
   
   Just to let you know, this has been discussed a few times on
   tech-userlevel (1999,2000), tech-net (1999) and current-users (1996).
   
   It is a good that this has PR. Also, important to note that UT_NAMESIZE
   should be increased for long usernames.



FWIW, the debian-bsd folks have a "utmpx" implementation that we
might be able to use, if people feel the need for utmpx.  i believe
the utmpx *interfaces* are defined in the single unix spec now?
