Reading up on that board, is the 2gig MMC big enough to support the Archlinux install with Minepeon. or will it be running from the SD slot?
Loads of space, I'm running Debian on my BBB, with several versions of cgminer and bfgminer on there, python, stratum_proxy, node.js, miner dashboard, hidapi, all the random packages for compiling, Apache, and there's still 600MB free on the eMMC.
