Only because there's been no better interface at that point (as was even mentioned on older dpkg-query man pages, exposing the db paths was never really a good interface, because among others it was susceptible to race conditions between concurrent dpkg and dpkg-query runs while changing db layout, or it could give people funny ideas about programatically modifying or removing such paths contents, etc). But then --control-path was intended only for read accesses for things like dpkg-repack or dpkg-reconfigure, never for *removing* files from the dpkg database. Removing such files from maintainer scripts is just *wrong*, the correct solution is to force an upgrade to a transitional package that does not contain conffiles/maintscripts. This option is going to go away relatively soon (in deprecation time terms); for 1.17.x I'm planning to make it issue warnings, something I didn't do for 1.16.x because the new interfaces were introduced pretty late in the release cycle and as such only available pretty recently, would have involved an annoying “transition”, and I didn't consider it fair at that point. I was planning on removing it on 1.18.x, but it might probably have to wait until 1.19.x. regards, guillem -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe".
