[Arm-netbook] Rebuilding official OS images?

Hi,

Are there scripts somewhere for building the official OS images for the A20 card, from official distro package repositories, using debootstrap or the equivalent tool for other distros?

I think it's important that the official OS images aren't just cobbled together by one person, with no one else knowing how to do it; in other words, the build process should be documented, reproducible, and ideally, fully automated.

Thanks, Matt
