We have a custom board based on CM3 Raspberry Pi module.
Our system will require 2 custom overlay files ( .dtbo) to be copied into /boot/overlays
We will use BalenaCloud for our fleet management.
If BalenaOS is updated via BalenaCloud. Will our custom .dtbo files be preserve inside /boot/overlays directory ?
In other words. How to add custom overlay .dtbo files to balenaOS making sure they will be persistent across balenaOS updates?
