Good morning. It's September 4th, and today's briefing centers on a single but significant architectural shift.
Pull request 958, from developer ryaneggz, closes out issue 956 and touches related work in issues 960 and 273. The change draws a clear line of responsibility inside the container: systemd now acts as process 1, owning process supervision at the OS and container level. Open Harness itself steps back to focus purely…
Concretely, the setup now runs two systemd services. One handles bootstrap as a one-time task, calling the existing entrypoint script without changing its behavior. The other runs the cron runtime continuously, under a dedicated sandbox user. Notably, the description calls out what's being removed as much as what's…
Why this matters: mixing scheduling logic with process supervision is a common source of subtle reliability bugs — orphaned processes, unclear restart behavior, unpredictable signal handling. By delegating supervision to systemd, a mature, well-understood tool built exactly for this job, the system gains more…
This is a broad change, spanning the Docker file, Docker Compose configurations, the entrypoint script, and both bootstrap and cron…
