# To reproduce on sid:
#
#    apt-get install gcc make bc gcc-aarch64-linux-gnu qemu-system-arm qemu-user-static
#
#    # build a kernel
#    curl -O https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.5.tar.xz
#    tar xfv linux-4.4.5.tar.xz
#    cp config linux-4.4.5/.config
#    cd linux-4.4.5
#    ARCH=arm64 make
#    cp arch/arm64/boot/Image ../Image
#    cd ..
#
#    # bootstrap a debian root filesystem
#    qemu-img create -f raw sid.img 1G
#    mkfs.ext4 sid.img
#    mount sid.img /mnt
#    qemu-debootstrap --arch=arm64 --variant=buildd --exclude=debfoster sid /mnt
#    umount /mnt
#
# That's it! It's the same process as building Debian images for xhyve. You'll have
# a sid.img root image and a bzImage kernel. Forget EFI.
