A SIGTERM handler is planned to be added to rclcpp/rclpy, implementing the same behavior as the current SIGINT handler.
rclcpp draft PR: https://github.com/ros2/rclcpp/pull/1771
The plan is to make it optional, a flag to disable it can be passed to init(), which will be ON by default.
There’s a small chance of regressions, so if you’re aware of any or if this affect your code after it gets merged, please let us know.
There’s also a plan to backport the option to old releases, but in that case the option will be OFF by default.
Best,
Ivan
