 utmp entries are created by ssh logins and reboots/shutdowns,
 but not for *any* console or telnet logins.  this is the problem.

 because i maintain several BSD systems, and i have
 a stripped custom /etc directory that i use for
 all of them; for ease of set-up and maintenance.

 reboots+shutdowns and sshd make correct utmp entries.
 login and telnetd do not.  i would like to know if
 there is a "manual" test i can do to isolate
 the problem.
