Hi, just curious, any reason this is using Arch as a base instead of a Debian base? I understand if you want to target specifically the RPi first but I think that using Debian will make it easier to port to other arches in the future (specifically armhf for the BBB and other more modern CPUs.)
I saw this as well https://bbs.arkos.io/t/why-arch-linux-why-not-raspian/43 but still think you should consider moving over... :P
Anyways, very cool project!
