+Moving conffiles between packages, redux
+
+I spent far too much of today cleaning up an upgrade bug to do with
+conffiles, which I suspect also affects other packages that have attempted
+to work around dpkg conffile prompts when moving conffiles between packages.
+If you maintain such a package, please review your code to make sure that it
+works properly when upgrading both with sarge's dpkg and with etch's dpkg.
+See <a href="http://lists.debian.org/debian-devel/2006/12/msg00647.html">my
+debian-devel post</a> for a full description.
