1st, the only cygdrive prefix that works on my system is /cygdrive/.
2nd, no matter what I set the prefix to /cyggdrive/ is the only
     prefix that works.
3rd, even using your suggestion of 'mount -c -b -s /IIFOIALIP', for
     example:

cd /IIFOIALIP/c/ # does not get me to c:/, whereas
cd /cygdrive/c/  # gets me there before during and after!!

Quite apart from the above:

Why (how is it that) I can get /zc ... /zy to show up in the output of 'ls /',
and I can do a cd to any of "/z?", without creating respective directories in /
of /zc .. /zy?

I submit to the group that whatever inconsistency in implementation or
documentation is behind these problems, is the source of numerous
configuration problems that people are having. I have run into this
problem so many times that I refuse to let it rest until I understand
it.

I'm not getting the joke, and more importantly the point! Could someone
else jump in here who is not as proud of their own sense of humor.

There I go where? I am not installing anything as "SYSTEM". Cygwin
setup (?) must be doing it? Why? How? How do I keep the mismatches
from occurring again?

For the third time, why do I have to explicitly specify '-s' and '-b'
when the man page says they are each the default?

What other sub-root directories besides /usr/bin /usr/lib require mounting
for a valid Cygwin configuration?
