utmp concepts are ancient. It is indexed by the tty/pty number so can grow
rather large but it should be a sparse one too. I remember talks about
replacing it with something a bit more modern. Backward compatibility is
assured through login(3) although it would break programs digging in the
utmp file itself. SVR4 had utmp/utmpx and setutline/getutline BTW...
System V has a better interface to utmp than BSD; it dynamically allo-
cates entries in the file, instead of writing them at fixed positions
indexed by position in /etc/ttys.
