It's a different line of development, dating back ten years or so.  BSD
developed off the V7/32V code base, in its own direction, while SysV traces
back thru SysIII to PWB, very roughly.  (PWB was a slight tangent, about
between V6 and V7 in time.)  SysIII picked up some V7 features, but then
mostly went its own way.

The real difference is the amount of cru^H^H^Hfeatures added to the two
systems over the years.  BSD hasn't been reluctant to add goo, but they
just can't keep up with the commercial development.
