I suppose so, I wasn't even sure how to build an image WITHOUT busybox - but I'm sure it's doable, and the RDEPENDS should reflect the dependencies accurately. I've updated the patch in the branch: http://git.yoctoproject.org/cgit.cgi/poky-contrib/commit/?h=dvhart/tiny&id=ed5ded75a66c6ae0defaef6301e333615f71d616 Thanks for catching that. -- Darren Hart Intel Open Source Technology Center Yocto Project - Linux Kernel
