You can always override it from local.conf using a _forcevariable override (which used to be named "_local", in fact, but that terminology turned out to be a bit confusing), or a _MACHINE override of course. So I don't think there is any major problem here. But, that said, it probably is true that the semantics of ??= are less surprising for users (since it isn't position-dependent in the way that ?= is) which might make it a better choice for image.bbclass. p. _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
