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.
EV-OS is an operating system which runs in real mode on the x86 platform. The system must be booted and run from floppy disk. The user interface is command-line based. Application programs must be prepared for operating system. EV-OS application programs can be developed under the Windows operating system, and a special tool is used to transfer files from Windows to EV-OS. EV-OS is written in assembly and the transfer program is written in C. The downloadable package contains an executable image file, the source code of the operating system, and some installation documentation.
SOSSE (Simple Operating System for Smartcard Education) is a free smart card operating system. It is implemented in C and assembler for the Atmel AVR smart cards (Funcard, PinkCard, Jupiter). The aim of this project is to provide something like Linux for smart cards, which is a market full of NDAs. SOSSE should make it possible to learn about smart cards, and to implement and test your own ideas.
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.
