The STUBS Toolchain and Utility Build Suite is a set of scripts which, together with a set of pre-written configuration files, builds one or more software packages in sequence. STUBS is designed to work in very minimal environments, including those without "make", and URLs are included so source and patches can be downloaded as necessary. Configuration files and scripts are provided which create boot media for Franki/Earlgrey Linux (one of several example busybox- and uClibc-based Linux environments) and the intention is that STUBS should be able to rebuild such an environment from within itself.
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.
Stem Desktop is a minimalistic Debian desktop for low-end hardware with limited memory (166Mhz / less than 64M). The goal is to find programs that have the smallest possible memory footprint. After installing *.deb packages on top of clean Debian, the desktop is ready to accept graphical logins.
OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
