-# The serve script drives `podman run` directly (image entrypoint is
-# overridden to `vllm serve`) and blocks on the container, so a container
-# death is a non-zero ExecStart. NOTE from frank-primary's experience:
-# vLLM's API server can drain and exit 0 after an engine fault, so the
-# restart policy MUST be always, not on-failure.
