Build SilverMetal Linux ISO (reproducibility-gated) / build-and-verify (push) Failing after 15m34s
Run #4258 cleared the systemctl shim only to die two seconds later on the *next* expectation derivative-maker has of a real systemd host: its sources.list points at http://127.0.0.1:9977/debian (the approx package-cache socket-activated by systemd) and apt-get update could not reach the daemon because nothing was actually started by the no-op shim: Err:1 http://127.0.0.1:9977/debian trixie InRelease Could not connect to 127.0.0.1:9977 (127.0.0.1). - connect (111: Connection refused) Whack-a-mole'ing each service derivative-maker tries to start (approx today, then journald, then systemd-logind, then who-knows-what tomorrow) is going to keep failing for a while — derivative-maker is fundamentally designed for a real systemd-managed Debian host. The container pattern upstream itself ships (linux/build/derivative-maker/docker/) runs systemd as PID 1 inside the container; this commit adopts that approach. Architecture: - PID 1 in the build container is now systemd. Upstream's vendored entrypoint.sh records the user-supplied command into /etc/docker-entrypoint-cmd, captures env into /etc/docker-entrypoint-env, masks irrelevant units, and execs systemd. systemd boots, docker-entrypoint.service runs the command, docker-entrypoint-stop.sh propagates the exit code via `systemctl exit <code>` so the container exits with the right status. - The four entrypoint files (entrypoint.sh, docker-entrypoint.service / .target, docker-entrypoint-stop.sh) are vendored at linux/build/docker/systemd-entrypoint/ rather than COPY'd from the submodule path — Docker build context can only reach below itself, and bumping is tracked in that dir's README. - Container runtime now requires --cgroupns=host, --tmpfs /run, --tmpfs /run/lock, and -v /sys/fs/cgroup:/sys/fs/cgroup:rw so systemd can manage cgroups properly. -t allocates a TTY, satisfying entrypoint.sh's `[ ! -t 0 ] && exit 1` check in CI where stdin is otherwise /dev/null. - User renamed builder → user (uid 1000, passwordless sudo) to match upstream's USER=user / HOME=/home/user convention. chown in build.sh now uses uid 1000:1000 so it's name-agnostic. - Image package list grew to match upstream's derivative-maker-docker-setup (sq stack + dbus + approx + the rest) plus our ISO toolchain (live-build / debootstrap / xorriso / squashfs-tools / etc.). Snapshot.debian.org pinning is preserved (same APT_SNAPSHOT_URL, two-phase install pattern). Verified: Smoke test on 10.0.0.51 — `docker run --rm --privileged --cgroupns=host --tmpfs /run --tmpfs /run/lock -v /sys/fs/cgroup:...:rw -t <image> /bin/bash -c 'echo OK'` — booted systemd, ran the command via docker-entrypoint.service, captured the output, shut down filesystems and exited cleanly. build.sh BUILDER_IMAGE pin → sha256:dc9dd29d…8811. Image rebuilt natively on 10.0.0.51, pushed to docker-registry.silverlabs.uk. The systemctl shim is removed by virtue of the Dockerfile rewrite — real systemd makes it unnecessary. The previous "iter6 / iter7" intermediate digests stay in the registry until we GC; the live one is m1.1-iter8-systemd. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
