Given: TC decision on "Merged /usr" https://bugs.debian.org/914897 The short of it, as I read it, is that non-usrmerge systems will be unsupported for bookworm, or did I misread that? I would almost think it makes more sense to *not* test usrmerge for bookworm, but continue to test it for bullseye and unstable (and experimental) in the reproducible builds infrastructure. This is my quick rationale for why I think that: * bullseye has been doing usrmerge variations for it's entire development cycle, it seems odd to change now. * Keeping unstable/sid with usrmerge variations is good for QA, as it does occasionally catch deeper issues. * Not doing usrmerge variations for bookworm is consistent with the plan for the next release (though we should have usrmerge always enabled then, as opposed to only building with non-usrmerge). It is also similar to build paths (which are not tested in the "testing" suite), a lower bar for the "testing" suite, as it is a relatively easy thing to workaround for reproducibility. But, I've only caught a small part of this thread, so maybe there's more to it. :) live well, vagrant
