Great job,
One comment, "second-stage" doesn't have to be made on OpenELEC, it can be done
on your host using /usr/bin/qemu-arm-static
code:
- apt install qemu-user-static
- host:# cp /usr/bin/qemu-arm-static debian_armhf/usr/bin/ && chroot debian_armhf && rm debian_armhf/usr/bin/qemu-arm-static
- I have no name!@host:/# ./debootstrap/debootstrap --second-stage
