TC decision on "Merged /usr"
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. :)
