Upgrading my stretch box to buster, I got a lot of these familiar prompts, and one very strange one from samba-common that used whiptail (debconf?) and didn't even use a unified or context diff or set DPKG_CONFFILE_OLD/NEW. (I should probably investigate what it's doing and file a bug about that—NOT expected behavior!)
But samba's behavior got me thinking that it ought to be possible to change the diff options or the pager or both. Seems that the pager is configurable, so colordiff can be inserted there. But if you have a preference for a different kind of diff, that's still not an option. Seems I'd kinda like the option to throw the old and new conffile at vimdiff so that I could quickly make whatever changes I wanted to, since that's what I usually do anyway. But it seems the diff-side of things is all hard-coded for the time being. Essentially, "subscribe", along with the added thought that someone might want to be able to use a diff-merge tool there rather than just a diff tool. Joseph
