Creating a Fedora Remix for ARM

Fedora Guidelines

Using Appliance-Tools on an ARM Host

To create a disk image remix for Fedora you will need to run 'Appliance-Tools' on an ARM host. For those without ARM hardware, this can be completed using QEMU and A15 emulation which can utilize more RAM. If you have ARM hardware you can safely ignore the QEMU portions.

Download the Fedora 20 Disk Image

First download the Minimal disk image for Fedora 20 and unpack.

wget http://download.fedoraproject.org/pub/fedora/linux/releases/20/Images/armhfp/Fedora-Minimal-armhfp-20-1-sda.raw.xz
unxz Fedora-Minimal-armhfp-20-1-sda.raw.xz

If needed install 'libguestfs-tools' to extract the boot files and expand the disk image to make room for our remix image.

sudo yum install -y libguestfs-tools
sudo virt-copy-out -a Fedora-Minimal-armhfp-20-1-sda.raw /boot .
qemu-img resize Fedora-Minimal-armhfp-20-1-sda.raw +10G # change this value to your desired size, it will need to be adequate for your disk image

Use QEMU to boot the new disk image using the vexpress-a15 dtb allowing for increased RAM usage.

qemu-system-arm -machine vexpress-a15 -m 4096 -nographic -net nic -net user \
     -append "console=ttyAMA0,115200n8 rw root=/dev/mmcblk0p3 rootwait physmap.enabled=0" \
     -kernel boot/vmlinuz-3.11.10-301.fc20.armv7hl+lpae \
     -initrd initramfs-3.11.10-301.fc20.armv7hl+lpae.img \
     -dtb dtb-3.11.10-301.fc20.armv7hl+lpae/vexpress-v2p-ca15_a7.dtb \
     -sd Fedora-Minimal-armhfp-20-1-sda.raw
