You must execute this on a text mount.

The easiest way to achieve this is to ensure that you are on a
drive that is not mounted.

For example, on my machine, if I have the following mounts:

c:\cygwin\bin /bin
c:\cygwin\usr /usr
c:\           /

To reproduce the problem, I go to drive d: (not listed in the mounts).

% cd /cygdrive/d
% ...
