System VI is really System V Release 2.0.  The naming convention was
changed to "nail down" the System V part.  Some SVR2 code still has
6.0 embedded in the comments.

I haven't heard of any 9th Edition; the System V numbering should
be standardized now on Release numbers.  Release X.Y.Z is major release
X, enhancement Y, bug-fixes Z.
