It is a small and exciting project just for fun as “Porting Inferno OS to Raspberry Pi”. Of course to run it there as native, not hosted. It was always declared that this OS is very simple for porting to new platforms, so let’s just research this and reach new distilled experiences of system programming. Also this OS is very small, simple and easy to tweak for research purposes.

It is organized it as some set of small labs with very detailed steps of what is done to reach results and make everything easy to reproduce.

To keep track of codebase of the Inferno OS on Raspberry Pi Labs we created the google code project to keep the repository and do other stuff related to the labs managements:
