But perhaps an option to save the current mount points somewhere would be useful in case the purpose of the uininstall is not removal for it's own sake but removal in order to perform a clean install, with subsequent restoration of the mount points. In other words insert a mount -m command before the first umount. -- davidp / DavidPostill -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
