How do you achieve this? The conffile questions are displayed after the new package is unpacked, so isn't a failing postinst all you can get? How do you get back to the old version? Yet an other approach: The teTeX packages have the problem that if some conffile questions are answered "no" and the old versions kept, the postinst will fail when building the formats. Instead of trying to do that, we check for the critical changes, and let the postinst exit with a debconf error message. (In fact it's tex-common's postinst).
