Hi all,
Just received my Samsung Chromebook ARM. Of course I want to put Arch on it (Chrome OS is nice, but too limited).
The solution provided by crouton (https://github.com/dnschneid/crouton: install another Linux distribution in a chroot, and run both simultaneously) is more attractive for me, at least for the time being, since, from what I heard, Arch is not 100% functional on the platform yet, and I don't want to get rid of Chrome OS just yet ,-)
Anyway, crouton is for Ubuntu only, so I ported the scripts so that they would work for Arch Linux:

Arch x86 is not supported, but it can be added without too much effort. Also, I only ported the xfce target (no other WM).
Please give it a try!
