I've prepared a fix for this along the lines I suggested. It proved awkward to choose between mv_conffile and rm_conffile due to the multi-stage nature of maintainer scripts, so I ended up using rm_conffile and inserting some code in the postinst script to capture the dpkg-bak file and rename it in the event that it had been modified.
If anyone would care to review and perhaps upload it, the dsc is at http://mentors.debian.net/debian/pool/main/i/inn2/inn2_2.5.3-1.1.dsc I am happy to deal with the unblock etc but would appreciate sponsoring for the upload. Failing that I shall go bother Mentors as usual :-) Nick -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
