Heh, I'm happy to try to go into more details but I wanted first to explain the general principle and see how people would react to it. > FWIW I don't think this is inconsistent with what Dustin was > suggesting --- dotdee would just be one example of a > dpkg-conffile-handler program. Yes, I even mentioned this case as an example. :-) > So the question becomes, where do the pristine conffiles get written, > and when does the conffile handler program get called to deal with > them. The closest compared to now is that have the pristine conffiles extracted where they are expected with the usual .dpkg-new suffix but to give the explicit path to the dpkg-conffile-handler so that dpkg is free to use something else later on. In theory the conffile handler would be called exactly at the time where dpkg renames .dpkg-new files during the --configure (i.e. before the postinst is run). > I confess that I'd prefer a hook specified on the commandline over > alternatives, since it would make experimenting with e.g. debugging > options a little easier.

The alternative system is cleaner to predict the behaviour of which package is going to have precedence should several conffile-handler be registered. But we can certainly have a command-line option too for experimenting (or even just to be able to write non-regression tests). > I'd also prefer if, at least to start, there is only one conffile > handling program so people can experiment with what a good stackable > interface looks like (those are hard) outside of dpkg. Trust us to accept only good stuff in dpkg. :-) Cheers, -- Raphaël Hertzog ◈ Debian Developer Follow my Debian News ▶ http://RaphaelHertzog.com (English) ▶ http://RaphaelHertzog.fr (Français) -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
