attached my solution to re-install or duplicate the packages of an 
existing installation.


$ ./cyg-reinstall.sh
Usage :  cyg-reinstall.sh [ -A | -I | -f filelist ]
   create cyg-reinstall-{ARC}.bat from
   options
     -A  :  All packages as reported by cygcheck
     -I  :  incomplete packages as reported by cygcheck
     -f  :  packages in filelist (one per row)

$ ./cyg-reinstall.sh -A

and the batch file is ready

$ ls -s cyg-reinstall-x86_64.bat
32K cyg-reinstall-x86_64.bat

$ head -c 100 cyg-reinstall-x86_64.bat
setup-x86_64.exe   -P 
_autorebase,_autorebase,_update-info-dir,a2ps,adobe-source-code-pro-fonts,adob
