Yes indeed, and Mike Nicholl discussed the gotcha in the T.O.M.S. post
on 27 Aug. If you don't change the HardDisc4 pathname, it *will* still
point to hard disc drive C: in the host computer.
To summarise: You can freely run VirtualRPC (and RISC OS) from a
simple *copy* of the main VirtualRPC installation.
However if, say, you open the HardDisc4 mount on the copy, that will
still be pointing to hard disc drive C: in the host computer.
So if for some reason you wish to access HardDisc4 on the *copy*, you
will indeed need to amend the pathname to it (or alternatively set up
a new mount for it).
But IMHO the *copy* is then no longer 'benign'. If you change the
contents of the copy HardDisc4, they will no longer match those of
HardDisc4 on Drive C: in the host computer. So if the host drive C:
should become corrupt, you can't then simply copy-the-copy back to it.
