Philipp Wagner has managed to get the new Firefox OS built and working on a Raspberry Pi. This is an immense achievement as it will truly give us another ‘flavour’ of OS for the Pi. At the moment, the OS doesn’t do very much – it boots but no input devices can be used, so I consider this an ‘alpha’. His development path implies a “release fast, release often” strategy so it will be interesting to see how it develops. He has blogged about this first release here.
