I have never used dpkg-maintscripthelper myself, but the documentation suggests that dpkg-maintscripthelper is not able to do that (the directory part) yet: Current implementation: in the preinst, it checks if the conffile was modified and renames it either to conffile.dpkg-remove (if not modified) or to conffile.dpkg-backup (if modified). In the postinst, the latter file is renamed to conffile.dpkg-bak and kept for reference as it contains user modifications but the former will be removed. If the package upgrade aborts, the postrm reinstalls the original conf‐ file. During purge, the postrm will also delete the .dpkg-bak file kept up to now. I would report this as a dpkg bug. -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
