VTServer/etc for V6 Unix

[Noel Chiappa]

The fact that the installation procedures for V6 and V7 are wholly different,
in their technical detail, was apparently not well known.

The 'Setting up Unix' documents are more checklists, they don't go into a lot
of detail as to what is actually happening, so I have prepared two pages on
the Computer History wiki:

  http://gunkies.org/wiki/Installing_UNIX_Sixth_Edition
  http://gunkies.org/wiki/Installing_UNIX_Seventh_Edition

which go into more detail on what is actually happening.
