Hi Martin, its Yocto chant #1: "Recipe data is local, configuration data is global."
Means: whatever happens in a recipe, other recipes can't see it. Whatever happens in a configuration file (local, machine, distro), it is visible everywhere. An image is just a recipe, in the end - so whatever you do there, it cannot affect the distribution. In a nutshell: you can't set DISTRO_FEATURES in an image.
