Whoa ... Cool... <-- my best Keanu Reeves impression.
Don't know if you need the help, but I'm kinda new to Arch in general and REALLY new to Linux on ARM machines, but I got like four pi3's. I might be able to help test if you can point be to where I can DL dev versions of Aarch. Lemme know what you want me to test and I'll see what I can do. (I'm coming from Debian distros, Netrunner and BunsenLabs).
