Package: release.debian.org Severity: normal Tags: buster User: release.debian.org@packages.debian.org Usertags: pu X-Debbugs-CC: dimitri.ledkov@canonical.com debian-boot@lists.debian.org debian-wb-team@lists.debian.org Dear release team, While preparing for the usrmerge transition as per [0], we have done some work on debootstrap [1] to ensure that, as per CTTE decision, buildd machines (and CI machines) can remain unmerged-usr. The new version of debootstrap with these changes is in unstable, testing and stable-backports. While talking with the buildd team, it was noted that some buildd machines are still running oldstable, and there is no hard deadline for the upgrade to stable. This means stable-backports is not enough to ensure we can begin the transition, and blocking it on the buildd full upgrades (which is difficult and time consuming) would put unduly pressure on the DSA team and risk long delays, as the Bookworm freeze approaches. A selected backport of the changes for stable-proposed-updates and oldstable-proposed-updates seems like a safe approach that removes the buildd team/DSA from the critical path, and the buildd team/DSA would prefer to go down that route. The backport was tested by creating a sid chroot with local packages that pull in usrmerge|usr-is-merged, and veryfing that with --no- merged-usr and/or --variant buildd the chroot is still unmerged-usr as expected. Debdiff attached. [0] https://lists.debian.org/debian-ctte/2022/07/msg00019.html [1] https://salsa.debian.org/installer-team/debootstrap/-/merge_requests/71 -- Kind regards, Luca Boccassi
