I have modified setup.exe to honor existing mount points.

If there are no mount points then setup.exe will use the same procedure
as previously.

There is no need to run a heuristic analysis on the root directory to
see if there is a "valid" installation there.  The user can install as
much or as little as they want.  They can have no root mount but a
/usr/lib mount.  In that case, we'll create a new root but install
/usr/lib files where the mount points.  We just honor whatever they are
using.
