  Hi , 

  I have generated and instelled libcap-dev, licap-bin packages for your yocto image in order to use capabilities .

  I have also actived options kernel .config , however , it seems that the ext4 FS does not contain user_xattr extension. The commands getcat or setcap gives output :  Failed to set capabilities on file `usr/bin/app1' (Operation not supported)

  Do you how to active Extra attributes on Yocto rootfs ?
