You can do some mount-based rules there as well, but that gets trickier
still to document / make portable.

I honestly don't know how well all of the tooling would work
containerized, especially since we're talking about dynamically
appearing/disappearing devices (ie we run sd-mux-ctrl to tell the sd-mux
board via USB to present the SD card to us as a mass storage device,
mount it via UUID, copy things, unmount, tell the sd-mux board to
present it to the device under test now instead).
