Max,

You should stay out of editing the registry and use some Cygwin
programs which know where to look and what to change there.  I am using
a batch script to switch between various cygwin versions installed on
my computer.  It essentially does the following:

@Echo off
Rem Edit cygwinRoot to match your drive\cygwinDirectory or just set it
to %1\ and pass it as a parameter to the script
set cygwinRoot=J:\cygwin\

set cygwinBin=%cygwinRoot%bin
%cygwinBin%\umount -U
%cygwinBin%\umount -S
%cygwinBin%\umount -c -u
%cygwinBin%\umount -c -s

rem Check to see if there is anything left
%cygwinBin%\mount
%cygwinBin%\mount -p

%cygwinBin%\mount -c -b -u /cygdrive
%cygwinBin%\mount -c -b -s /cygdrive
%cygwinBin%\mount -b -s %cygwinRoot% /
%cygwinBin%\mount -b -s -f %cygwinRoot%bin /usr/bin
%cygwinBin%\mount -b -s -f %cygwinRoot%lib /usr/lib

if exist "%temp%" %cygwinBin%\mount -b -s -f "%temp%" /tmp


If you plan to run it on NT hosts save it as a .cmd file in your
removable media cygwin root. You can then figure out on the fly what
that dir is using:

rem The root is the directory of this file
rem NOTE: It will have a trailing \
for /F %%i in ('ECHO %0') do set cygwinRoot=%%~dpi

The alternative is to write your own C code that runs the umount and
mount commands. It will work on all win32 hosts.

Hope it helps,
Doru Carastan
