We have one AEP config file per board. As we can use /dev/serial/by-id/ path in our current test env, we don't have to update it as the config file is always valid Then select the right config file according to the board we want to use for our test > > At the moment, in LAVA we're passing the appropriate /dev/ttyACMx > device node into the LXC as we start things up.
