We build the OS, it runs on the target. This is building a general purpose OS, and then having it build itself out more. It doesn't feel like an embedded workflow. That said, there are valid use cases, but I don't consider this a particularly high priority at the moment. I'm happy to hear other thoughts on why this should be bumped in prio though. -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
