Source Ruckus Linux is an embeddable, robust Linux meta-distribution. It's a collection of build tools, source packages, scripts, and documentation all ready to be built into a Linux distribution. It can be used out-of-the-box, but its real strength lies in being used as a base for your own distribution. In other words, it exists purely to be forked, although it can be used as-is.
Chakra Linux is a Linux distribution that combines the simplicity of Arch Linux with KDE. It is fast, user-friendly, and extremely powerful. It can be used as a live CD or installed to hard disk. Chakra is currently under heavy and active development. It features a graphical installer and automatic hardware configuration. Chakra provides a modular and tweaked package set of the KDE Software Compilation with a lot of useful additions. It features the concept of half-rolling releases and freshly cooked packages and bundles. It is designed for people who really want to learn something about Linux or don't want to deal with administrative overhead.
Lincom is a Linux distribution created by volunteers who devote part of their time making Lincom an easy-to-use operating system. Lincom does not brand or make distribution-specific any part of software included, therefore, it is easy to customize to the user's taste. Lincom is fully customizable and the compilation of software that Lincom uses to create its distribution is easily available with full documentation of what Lincom does in terms of branding or customization.
Nightwing allows the creation of quickly deployed wireless networks without the need to make complicated configurations. With the implementation of a Mesh technology called B.A.T.M.A.N, Nightwing allows the extension of wireless networks with a simple way of adding devices that works with minimal human intervention. It has public and private connection interfaces, and the ability to filter content using OpenDNS. It is designed with security in mind, and has low hardware requirements.
haveged is a daemon that feeds the /dev/random pool on Linux using an adaptation of the HArdware Volatile Entropy Gathering and Expansion algorithm invented at IRISA. The implementation attempts to be self-tuning on a wide variety of hardware and includes runtime validation testing. The tarball uses the GNU build mechanism and includes a devel sub-package, self test targets, init system options, and spec file samples for building an RPM. haveged may be used independently of the /dev/random interface through the filesystem at the command line. haveged functionality may be incorporated directly into other components directly through the devel sub-package.
Portable Linux is a tool that lets you create bootable USB and removable drives using popular Live CDs based on Casper (like the Ubuntu family of distributions). It sports some unique features. The live setups it creates let you use the remaining disk space on your USB drive to store and transport files between computers, as usual. If your distribution supports persistence, the files and settings you edit on your live Linux distribution are persisted across reboots. Finally, you can access the area used to store your files from within your Linux distribution.
Uruzuki GNU/Linux is a virtual distribution, meaning that there aren't ISO images for installation via CD. It is a complete distribution that resides on an Internet repository. Its applications can be installed on a new minimal Debian system. The software in Uruzuki Linux is the same as that included in uzklive, its live port.
Tin Hat is a Linux distribution derived from hardened Gentoo. It aims to provide a very secure, stable, and fast desktop environment that lives purely in RAM. Tin Hat boots from CD, or optionally USB pen drive, but it is not a LiveCD in that it does not mount any file system from the boot device. Rather, Tin Hat employs a massive squashfs image which expands into tmpfs upon booting. This makes for long boot times, but remarkable speeds during human-computer interaction.
