What Linux distros will be supported at launch?
Debian, Fedora and ArchLinux will be supported from the start. We hope to see support from other distros later. We will be selling SD cards with the distros preloaded. (Sept 4 2011 – originally, this FAQ suggested that Ubuntu would be supported. Because of issues with newer releases of Ubuntu and the ARM processor we are using, Ubuntu can’t commit to support Raspberry Pi at the moment.)
