Hi Earnie,

Thanks for your reply.  I have commented below:

Ah! Since it says "warning", the "principle of least astonishment"
should not have been violated and therefore, the software should have
acted consistent with my first example, i.e., have done a "mkdir f"
before doing the "mount f: f/"?

At this point, I don't know what you mean by "non-list", so I can't
comment.

Based on the "side effects" of the command sequence, I agree. The
software should have "done it right" or only issued an error message
that said, effectively, "Hey dude, create the damn directory before you
do a mount!  Don't leave it up to me!" :-)

I figured this out but it still doesn't answer why the directory for f
(mount point) looks like any other directory but doesn't show up in an
"ls" in the root?

This confirms what I expected but why doesn't "f" show up in an "ls" in
the root (/)?

Sounds like the code needs a good "slap side da head"!  Unfortunately,
I'm not there yet.  Is it a problem with "mount", "ls", "cygwinxxx.dll",
or ...?

Thanks for your help!
