Its about 50KB for core-image-sato-sdk. Having them in a separate package seems not feasible now, because we can't make sure the package is generated after all other packages have finished their populate-sysroot tasks. But it's a good idea to populate the site config files only into the -dev or -sdk images. I'll rework the patch.
