Design a safe and stable build cluster for public ARM PPAs based on the OMAP4 Pandaboard

Registered by Oliver Grawert

With the availability of the TI OMAP4 Pandaboard, hardware is available to make it possible to set up a buildd cluster for public PPAs on launchpad. This spec is proposed to design a safe and stable hard and software implementation for this setup.
