All 4.4BSD systems put sendmail in /usr/sbin. System V puts it
in /usr/lib, but then, this is not the only archaic thing in
System V. Some 4.4BSD systems still have /usr/lib/sendmail as a
symlink to /usr/sbin/sendmail for compatibility reasons. BSDI 3
had, if I'm not mistaken. BSDI 4 doesn't.

4.4BSD has /usr/libexec and /usr/libdata for some things
previously stored in /usr/lib. /usr/lib is for libraries,
period.

But /usr/libexec isn't, because sometimes you still want to run
sendmail by hand.

They seem to have learned something from BSD. Over several
years, Linux distros acquired /usr/libexec, /usr/share, etc.
