arkOS

 arkOS  is a software stack designed to make the installation and management of self-hosted services such as email, web servers, or a private cloud easy and intuitive. arkOS focuses on saving data on user-owned hardware and currently supports Raspberry Pi, Cubieboard, and BeagleBone as platforms.
