The only thing I would change is to save the state of the mounts within 
the uninstall script (just before uninstalling), rather than the state 
at install time when /etc/postinstall/gen-uninst.sh was run.

I also added a warning at the beginning, since this performs such a 
drastic operation, even though the UN*X philosophy is to do what the 
user says, no matter what, as in "rm * .o":

------ BEGIN gen-uninst.sh ------
#!/bin/sh
CYGDIR="`/bin/cygpath -aw /`"
cat > /uninstall.bat <<EOF
@echo Warning! This will remove all of Cygwin!
@echo Use Ctrl-C or Ctrl-Break now to abort. Any other key will continue.
@pause
$CYGDIR\\bin\\mount -m > %TEMP%\\saved-mounts.bat
$CYGDIR\\bin\\umount -s -A
$CYGDIR\\bin\\umount -A
copy $CYGDIR\\bin\\cygwin1.dll $CYGDIR\\bin\\regtool.exe %TEMP%
$CYGDIR\\bin\\rm -rf /
del /s $CYGDIR
%TEMP%\\regtool remove "/HKLM/Software/Cygnus Solutions"
%TEMP%\\regtool remove "/HKCU/Software/Cygnus Solutions"
del %TEMP%\\cygwin1.dll %TEMP%\\regtool.exe
EOF
------- END gen-uninst.sh -------
