Of course, recent versions of most UNIX variants incorporate major
features from a variety of earlier versions of UNIX.  UNIX System V
Release 4.0, in particular, incorporates in a (hopefully consistent)
single system practically all useful features from previous 4BSD and
Xenix releases.

Yup.  Perhaps you should have explained that by "DAG" you meant Directed
Acyclic Graph: "directed" by the flow of time, "acyclic" since effects
cannot precede their causes, and "graph" since each OS release can be
treated as a node with having an effect on another OS release being
treated as a (directed) edge.

I personally am not a directed acyclic graph; I'm as loopy as they come.
