commit 8dfabe4056d243433925c627ae2e7fb4f0846d86
Author: Stefan Agner <stefan@agner.ch>
Date:   Wed Jan 23 00:31:17 2019 +0100

    initial commit
    
    Create Arch Linux ARM images using multi-stage Dockerfile. This
    works well with binfmt emulation and allows to generate images
    from scratch.
    
    Inspiration taken from:
    - https://github.com/archlinux/archlinux-docker
    - https://github.com/lopsided98/archlinux
