Debconf wasn't designed to serve the purpose to which you are trying to put it. "Debconf is not a registry." Suppose you have packages x and y with configuration files xconf and yconf. Your package z should contain a program that reads xconf and yconf and writes them out again with new values. If x and y have configuration utilities xcfg and ycfg then z should insofar as possible use xcfg and ycfg to make changes to x's and y's configurations. -- Thomas Hood
