Trying to add the hdmi hotplug udev rule to the build environment, adding it in the same manner as the C2 hdmi config script doesn't work, it tells me the file/folder doesn't exist, I'm guessing then that bsp family tweaks isn't the place to add it?

If you are trying to add anything to BSP package you need to create that folder. https://github.com/armbian/build/blob/master/config/sources/meson64.conf#L57-L61 We are creating a deb file in tmp. https://github.com/armbian/build/blob/master/lib/makeboarddeb.sh#L214

Ah ok, so script works on temp directory that goes to a deb that gets installed.  I missed a step in what I thought was going on.  That makes much more sense.  Thank you!
