Source Mage GNU/Linux is a source-based Linux distribution based on a magical metaphor of "casting" and "dispelling" programs, which are referred to as "spells". In multi-tasking style, it downloads the sources in the background while compiling in the foreground. Source Mage's "sorcery" offers advanced package management, but retains the choices, options, and control not offered by many other distributions.
LinVDR is a small, lightweight, ready-to-run and easy-to-install distribution of VDR which can turn almost any PC with a DVB-s (digital satellite) card into a digital hard disk recorder.

GoboLinux is an alternative Linux distribution that redefines the entire filesystem hierarchy. There is no package manager: instead, packages can be managed directly through the filesystem. In GoboLinux, each program resides in its own versioned directory, such as /Programs/Xorg/7.1/, keeping applications self-contained and improving system maintenance.
