i have recompiled all with fedora and the build end fine without any package problem so when i start spark script work with fakeroot but ever empty file on /tmp/ROOT/dev if someone have an 7162 openpli nightly compiled please can upload here or on some free hosting for test on my amiko alien2 because will be possible at the moment that my box is not supported by duckbox. so if someone have a good dev.tar.gz i can try unpack it on release dir and rebuild the jffs2.img.............many thanks for your support.
edit1
i see now the fix for devs on master git by bonkel i retry rebuild my image.
