That's a concern if you're trying to create a package feed. But in that case you should already be taking care that BSP layers don't change the way recipes in common layers are built. ie this is something you would be controlling from a distro layer anyway. If you don't care about maintaining a package feed (which I guess is the majority of us?) then BSP layers which contain .bbappend files for recipes in common layers works just fine. > > Going back to the original question of whether cryptodev-linux should > > be enabled by default, I would say no.
