I have created 2 Fedora 21 images for the HummingBoard and Cubox-i. http://vps1.mkreder.com/Fedora-Mate-armhfp-21-5-sda.raw.xz MATE http://vps1.mkreder.com/Fedora-LXDE-armhfp-21-5-sda.raw.xz LXDE I will create a XFCE based image too, soon. In order to extend the root filesystem on this image, you need to run:
fdisk /dev/location-of-your-fedora-arm-media << EOF
e2fsck -f /dev/location-of-your-fedora-arm-media3
