Now that balenalib base images have been deprecated (as of 2025), I’m looking for guidance on the best current approach for handling udev functionality in balena applications.

Previously, I was using balenalib images with `ENV UDEV=1` to automatically handle dynamically plugged USB/serial devices. Now I’m migrating to standard `ubuntu:22.04` base images.

1. What’s the current recommended way to set up udev in standard base images for balena deployments?
2. Do I need to manually install udev, create entry scripts, and handle the privileged container setup myself, or is there a balena-specific recommended pattern?
3. Are there any balena-specific considerations or gotchas when setting up udev manually that I should be aware of?
4. Has balena published any migration guides or best practices for this transition from balenalib to standard base images?

For context, I need to detect and interact with USB devices that are plugged in at runtime, similar to what `UDEV=1` provided in balenalib images.

Any guidance or examples would be greatly appreciated!

Thanks
