Here are the batch files I use.  In their current state, they must
exist in the parent directory of the cygwin root, which must be named
"cygwin".

install.bat backs up the current cygwin mount table, then creates a
new table for the removable device.  It uses the users Windows %TEMP%
dir for /tmp, because I wanted to minimize writes to the flash disk.

uninstall.bat removes the new mount table, and restores the backed up copy.

--begin install.bat--
@echo off

for /F %%A in ('cd') do set WD=%%A

cygwin\bin\mount -m | cygwin\bin\sed s/mount/"cygwin\/bin\/mount"/ >
%TEMP%\cygwin-mounts
cygwin\bin\umount -c
cygwin\bin\umount -A
cygwin\bin\mount --binary --force --user %WD%\cygwin /
cygwin\bin\mount --binary --force --user %WD%\cygwin\bin /usr/bin
cygwin\bin\mount --binary --force --user %WD%\cygwin\lib /usr/lib
cygwin\bin\mount --binary --force --user %TEMP%\ /tmp
--end install.bat--

--begin uninstall.bat--
@echo off

for /F %%A in ('cd') do set WD=%%A

cygwin\bin\umount -c
cygwin\bin\umount -A
cygwin\bin\sh %TEMP%\cygwin-mounts
cygwin\bin\rm %TEMP%\cygwin-mounts
--end uninstall.bat--
