For now, because of lack of libc features, adding packages to poky-tiny is likely to fail. So the question here is, are we deciding that poky-tiny equals to 'limited-featured libc + tiny init + busybox"? If so, maybe we need to a mechanism to warn user when they try to add packages to poky-tiny. Besides, removing the libc features doesn't seem to have significant effects on the size of the image. chenqi@pek-qchen1-d1:~/poky$ ls -lh build-tiny/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/rootfs/lib/libc-2.17.so -rwxr-xr-x 1 chenqi chenqi 1.1M Jul 10 13:49 build-tiny/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/rootfs/lib/libc-2.17.so chenqi@pek-qchen1-d1:~/poky$ ls -lh build/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/rootfs/lib/libc-2.17.so -rwxr-xr-x 1 chenqi chenqi 1.5M Jul 3 11:23 build/tmp/work/qemux86-poky-linux/core-image-minimal/1.0-r0/rootfs/lib/libc-2.17.so Best Regards, Chen Qi
