Christopher, Yes I have read that section but it is not useful as selecting between bad/good is already the required workflow. The issue is that the documentation refers to using the packaging scripts in the debian/ subdir, which is not present and/or usable in the intermediate bisecting steps. I'm currently testing using this workflow, please advise if it is the correct one:
