though it does require changes for the nvidia.just and custom.just to be made in config ... but i think that's probably not a concern.
custom.just, it's currently holding anything added by startingpoint + anything the person making a downstream image wants to add to it (they fork startingpoint and add their own stuff to custom.just), so we can't include that one in the main config repo.include directive is on by default. Will we then switch profile.d to insert include /path/to/main.just etc? Or will we tell users to insert the modular pieces they want manually? I think automating it still makes sense for people who don't have a justfile yet. So it's good that we have this framework for patching the ~/.justfile now.custom.just is in an awkward spot atm.
