Multi-boot option for testing

Just an FYI. Alex at BerryBoot has kindly created a compatible OpenHD image, here - Berryboot Updated OS Images - Browse Files at SourceForge.net

There’s more about BerryBoot here: berryboot [BerryTerminal] but basically it allows you to have multiple OS on your Pi SD card, which is useful for when you use your ground Pi for a variety of things.
