This is the output to this question, much better explained than I could. I focused in the `Apparmor` part (point 5).\n\n`tempfile.gettempdir()` is the correct choice for your use case. Here\u0027s why:\n1. Semantic difference: state_path is for persistent state that must survive restarts (configs, PID files, sockets). Your \"first worker election\" flag is intentionally ephemeral - it must reset on reboot (which /tmp does automatically) and the PPID mechanism resets it on WSGI daemon restart.\n\n2. state_path is agent-centric: The help text says \"This directory must be writable by the agent.\" Your code runs in the neutron-server (API WSGI workers), not in an agent.\n\n3. Using state_path would be counterproductive: If the flag file persisted across reboots (in /var/lib/neutron), you\u0027d get stale election results when the service restarts with the same PPID (unlikely but possible with PID recycling on long-lived systems).\n\n4. Consistent with existing patterns: The two non-test tempfile usages in Neutron (BGP bridge, FRR driver) both use default temp directory for ephemeral files that do not need to persist.\n\n5. `tempfile.gettempdir()` respects environment variables: If an operator has AppArmor or other restrictions on /tmp, they can set TMPDIR/TEMP/TMP to redirect it. This is the standard mechanism. This is already used in other projects (oslo.service, oslo.concurrency).","commit_id":"bb7a563ed0b7c3f1b48323ec57a8938b81367d94"},{"author":{"_account_id":16688,"name":"Rodolfo Alonso","email":"ralonsoh@redhat.com","username":"rodolfo-alonso-hernandez"},"change_message_id":"9bc8f9ad0a3a0ff9d0fdcc30a0199ea6c4bff3ec","unresolved":false,"context_lines":[{"line_number":40,"context_line":"              The full path of the temporary file."},{"line_number":41,"context_line":"    \"\"\""},{"line_number":42,"context_line":"    ppid \u003d os.getppid()"},{"line_number":43,"context_line":"    _path \u003d os.path.join(tempfile.gettempdir(), file_name + str(ppid))"},{"line_number":44,"context_line":"    try:"},{"line_number":45,"context_line":"        fd \u003d os.open(_path, os.O_CREAT | os.O_EXCL | os.O_WRONLY, 0o644)"},{"line_number":46,"context_line":"        os.write(fd, content.encode())"}],"source_content_type":"text/x-python","patch_set":6,"id":"fb70eabb_7781ad70","line":43,"in_reply_to":"ea083475_50f074cd","updated":"2026-07-22 14:10:41.000000000","message":"We have other places in the code (recently added: `FrrVtyshExecutor`, BGP `Bridge`) where we use `tempfile.NamedTemporaryFile` without using the state_path.
