In an earlier response to the original question, Chris Faylor suggested
using 'mount -?' to get descriptions of options and that one of these
should help.  So I was trying out mount with different options, in
different ways, and came up with a new issue.

It appears that I can create an environment where / is mounted on 2
different locations, one stored at the system level and one at the
user.  It would seem to me to make sense that 'mount' should not allow
duplicates of system level mount points at the user level.  Is this a
valid conclusion?
