That would be nice, but isn't what the CTTE ruled as the implementation of the resolution (= no longer supporting non-merged-usr layout) is delayed until after the release of bullseye. That is also what the bullseye release notes say, too. Wouldn't it be kinda strange to have the chroots building the packages for the first bookworm release using a layout which isn't supported by bookworm itself… and wouldn't it be even worse if we change from the quasi-bookworm unmerged unstable chroots to the bookworm merged chroots [as unmerged isn't supported for them] for building the packages of the first point release? That is why I said freeze as I kinda doubt the release team would like to have a big change for bullseye after the freeze… > 2. bookworm release: systems must transition at or before the upgrade to > bookworm (bullseye systems are not required to transition until/unless > they are upgraded) The "at" in this sentence means that all bookworm packages must support unmerged as you can't guarantee that the transition happens before¹ and forces bookworm chroots to be unmerged as well as the packages built in them will be used to upgrade from bullseye as we don't do →.0 → .1 → … upgrades. That is of course in direct contraction to not supporting it anymore. Best regards David Kalnischkies ¹ well, you could by having $magic implemented with the essential set and shipped in something like base-files (= installed everywhere) to pre-depend on it from quite literally every package in existence. [shouldn't be a new package as release notes traditionally advice to run an upgrade without installing new packages first] Kinda doubt that would work in practice…
