Gentoox is a 'port' of Gentoo Linux to the Xbox. It comes in Pro and Home flavors, where Pro is a Stage 3 bootable distribution with nothing else added (for developers and pros to customize themselves), and Home comes with many packages precompiled and installed, making it ideal for beginners or people who want their Linux to work straight out of the box. Installation time is minimal and totally fuss free.
ClusterKnoppix is a modified Knoppix distribution that uses the OpenMosix kernel. It features an OpenMosix terminal server that uses PXE, DHCP, and tftp to boot Linux clients via the network. It also includes openMosix auto-discovery, cluster management tools, and an optional X environment.
slapt-get is an APT-like system for Slackware package management. It allows you to search Slackware mirrors and third-party package sources (such as www.linuxpackages.net) for packages, compare them with installed packages, and install new packages or upgrade installed packages, all with a few simple commands.
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. It contains VDR Admin for Web administration and Samba shares to upload your MP3 files or download DVD images made from your TV recordings.
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.
