Although other issues might > need to be solved.... sstate-cache already caches the results of the package builds (not just RPM). This is needed to be able to populate both the sysroot and the package set for the image generation step. To me what is a bigger deal is to break up the image generation into an external step.. so I can simply start with a set of packages and build them. (since sysroots and similar are not needed in this situation.) --Mark > -M > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto
