Anyway the best way to debug a scenario like this is to use bitbake -e and grep on the thing you are interested in. I tried to add a feature to local conf and, as i expected, EXTRA_IMAGE_FEATURES ended up overwritten by recipe. So IMHO the EXTRA_IMAGE_FEATURES variable in the image should be merged in the IMAGE_FEATURES above. I don't see the meaning of it. @g
