This is true; FWIW as the original author of that line in image.bbclass I wouldn't object to changing it to ??= though. Having said that, I would note that people are best advised not to try to set too much from local.conf, especially when it's stuff that affects what is in the final image. Anyone doing anything moderately custom should really have their own distro config. FYI, we now have a section in the Yocto Project development manual documenting this: http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#creating-your-own-distribution Cheers, Paul -- Paul Eggleton Intel Open Source Technology Centre _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
