Some checks failed
Build SilverMetal Linux ISO (reproducibility-gated) / build-and-verify (push) Failing after 18m13s
Run #4259 (the systemd-in-container debut) cleared every prior failure class, ran for 15 minutes, then died inside 1100_sanity-tests' aptgetopt_conf_add at: tee: /home/root/derivative-binary/30_derivative-maker.conf: No such file or directory last_failed_bash_command: tee --append -- "$dist_aptgetopt_file" > /dev/null Two compounding bugs: 1. **user_name resolves to "root" via $SUDO_USER** derivative-maker/help-steps/variables (lines 80-93) computes user_name with these fallbacks, in order: [ -n "$user_name" ] || user_name="$SUDO_USER" [ -n "$user_name" ] || user_name="$(logname 2>/dev/null)" if [ -z "$user_name" ] && [ "$(id -u)" != "0" ]; then user_name="$(whoami)" [ -n "$user_name" ] || user_name="$USER" fi build.sh enters the container as root (systemd's docker-entrypoint.service runs as root), then sudoes to user via `sudo --preserve-env -u user --`. sudo always sets SUDO_USER to the *calling* user (= root), regardless of --preserve-env. So variables.sh hits the first fallback and computes user_name="root", then HOMEVAR=/home/root, then binary_build_folder_dist= /home/root/derivative-binary — a directory that does not exist because root's home is /root (not /home/root). Fix: build-inner.sh now exports user_name=user before sourcing the config, satisfying the first-priority check in variables.sh and short-circuiting the SUDO_USER fallback. The comment in the script notes the failure mode for the next reader. 2. **Missing mkdir of derivative-binary** Upstream's derivative-maker-docker-start does: mkdir --parents -- "${HOME}/derivative-binary" before invoking derivative-maker. Our build-inner.sh skipped that because previous iterations didn't reach the point where it mattered. Now that we do, we replicate it. 3. **Output collection path correction** derivative-maker writes its ISO/manifest output into ${HOME}/derivative-binary (per variables.sh:109) — not into the source tree under linux/build/derivative-maker. The previous `find . -maxdepth 6 -type f -name "*.iso"` would have missed everything once we got that far. Updated to `find "${HOME}/derivative-binary" ...`. No image rebuild needed — this is a pure script-and-env change. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
