Hi, the transition to usrmerge as described in [1] is planned to start around 2022-09-15 (next Thursday).
init-system-helpers 1.65~exp1 in experimental adds the new dependency on "usrmerge | usr-is-merged" and will be uploaded to unstable to start the transition. Feel free to test and report any issues. Recent versions of debootstrap[2] will setup the usr-is-merged package to avoid installing additional dependencies required by usrmerge. The usr-is-merged package can also be manually installed in existing systems for the same reason. Debian's buildds will continue to use the legacy filesystem layout for Debian 12 (bookworm). We will send an announcement to debian-devel-announce@ once the upload to unstable happens. Ansgar [1]: https://lists.debian.org/debian-ctte/2022/09/msg00005.html [2]: debootstrap 1.0.114+deb10u1, 1.0.123+deb11u1, 1.0.127
