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.
Linux is a clone of the Unix kernel, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix kernel, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.
Loonix is a custom Linux distribution meant for server applications. It comes with only the latest up-to-date programs and applications, all specially configured for optimal performance and ease of use. Programs are neatly organized in structured directories, and strict security rules are in place for sensitive configuration files and other data.
openMosixLOAF (openMosix Linux-On-A-Floppy) is a single floppy openMosix Linux mini-distro designed for harddiskless systems or HPC clusters where only CPU and memory is needed. It has drivers for all PCI Ethernet NICs that the Linux kernel has support for (10/100/1000) and comes on only one bootable 1.6MB 3½" floppy diskette, ready to be a node in your HPC cluster.
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.
