dh has a new tool dh_missing which is a dh variant of our existing list-missing. notable disadvantage of the latter is that it is only used for core pkg-kde packages. all others previously had no useful list missing support. fortunately dh in bionic already runs dh_missing by default, alas, without any output enabled. We need to force output and have our tooling support parsing it so we get greater list-missing coverage!
[09:17] <sitter> so, for the record: dh_missing is basically the dh variant of dhmk's (pkg-kde-tools) list-missing.mk (i.e. with debian/not-installed support; something that was sorely missing from dh_install --list-missing). as mentioned by default dh_missing does nothing which is meant to change with compat 12, unfortunately bionic only has dh11, so we can't use dh12 for a while. all things considered we'll need support for dh_missing parsing (in our lint tech) AND [09:17] <sitter> quite possibly some hack to get it run with --list-missing even when compat isn't 12 [09:18] <sitter> could probably just divert the file and introduce a wrapper that exec's with --list-missing forced
