Um, no. *Policy* says that it may not be used as a registry. - Debconf answers are stored in /var/cache/debconf. Under the FHS, which is a mandatory part of Policy, the rules for /var/cache are that "[the] application must be able to regenerate or restore the data", and "the cached files can be deleted without data loss." *This precludes using debconf as a registry, and is by design*. Since the position of the debconf maintainer is that debconf should not be used as a registry, if you use it as a registry then *your* package, not debconf, is in violation of Policy. - Policy section 11.7.3 requires that "local changes [to configuration files] must be preserved during a package upgrade". Using debconf as a registry implies giving precedence to debconf over the contents of an edited configuration file. THIS IS A VIOLATION OF POLICY. Therefore, even if you resolve the above issue, Policy only allows you to use debconf as a registry *for information that is never written to a config file*. I'm not sure why you think Joey's expertise doesn't qualify him to make pronouncements about the use of debconf. Unlike you, he at least gets the answer right. -- Steve Langasek postmodern programmer
