prod_orchestrator::install_fresh now branches on the new
Config::use_quadlet_backends flag (default false):
* off (today's production behavior) — unchanged: runtime.create_container
+ start_container, container parented under archipelago.service's
cgroup, FM3 cascade SIGKILL on every archipelago restart.
* on — install_via_quadlet renders the manifest as a Quadlet unit via
QuadletUnit::from_manifest, writes it atomically into
~/.config/containers/systemd/, calls daemon-reload, and starts the
generated <name>.service. Container ends up under user.slice — no
more cgroup parented under archipelago, so archipelago restarts
don't touch the container's lifetime.
Default off so this commit is structurally safe to ship: nothing
changes at runtime until an operator opts in. Flip the default once
tests/lifecycle/run-20x.sh has gone green against the new path on
.228 + .198 (the v1.7.52 release gate).
Plumbing:
* config.rs — `use_quadlet_backends: bool` w/ Default false
* prod_orchestrator.rs — flag stored on the struct, threaded through
new(), with set_use_quadlet_backends(bool) test setter
* prod_orchestrator.rs — install_via_quadlet helper
* dropped the Phase-3.1 #[allow(dead_code)] markers on from_manifest /
parse_memory_mib / RestartPolicy::OnFailure now that the call path
exists; if a future revert removes the wiring, the warnings come back.
Tests: 624 passing, cargo check clean (0 warnings). Existing companion
behavior unaffected — render_skips_backend_directives_when_default
still passes byte-equal to before quadlet.rs grew the new fields.
