Damn Small Linux
DSL was originally developed as an experiment to see how many usable desktop applications can fit inside a 50MB live CD. It was at first just a personal tool/toy. But over time Damn Small Linux grew into a community project with hundreds of development hours put into refinements including a fully automated remote and local application installation system and a very versatile backup and restore system which may be used with any writable media including a hard drive, a floppy drive, or a USB device. hot
Puppy Linux boots into a 48 - 54M ramdisk, from a USB keychain disk drive, Compact Flash, Hard Drive, Zip Drive, Floppy, Network/Thin Client, CD-ROM or Mini-CD. No more distributions that only support a single boot media, puppy boots from 'em all. Read more hot
0sys is an effort to create the most functional UNIX environment in the smallest amount of code, in the most optimal manner. Written primarily from scratch (with concepts and
entire chunks of code taken from Busybox, util-linux, and others), it aims for portability and POSIX compliance. The sources include some GTK-based GUI utilities (including
a login client), as well as a stable, consistent, and flexible build system.
1diskxwin is a source dist to create a bootable floppy linux X window system. It has lots of stuff removed from the standard xfree dist to ease network bandwidth. it also lacks many packages from the full 2diskxwin source tree.
2-Disk Xwindow System
The distribution is intended to be a demonstration of Mungkie associates embedded appliance development environment, showing the sort of environment that can be created for small appliance GUI systems using less than 4Mb flash and 4Mb RAM.

The goal is to make it easily usable for people able to use linux yet have it boot off only a minimal number of floppies.
Antlinux will be a mini-distribution of Linux, with an eye on small footprint applications such as run-from-CD versions of Linux.
ariane is a bootable CD-ROM linux. It's the successor of giotto. While giotto booted a libc5 system with a linux kernel 2.0.37 from floppy disks, ariane comes with linux kernel 2.4.26 and libc6, version 2.2.4. It boots (just as giotto) into your computer's RAM.
BasicLinux is designed specifically for old PCs. It uses a small kernel and busybox to provide a low-RAM Linux, capable of browsing the web, doing email, and functioning as an X terminal. The current release of BasicLinux is particularly suitable for old laptops -- it has PCMCIA capability and includes MagicPoint (a presentation tool similar to PowerPoint).
the LEAF "Bering" distribution is derived from Charles Steinkuehler's Dachstein (rc2). It differs from it on two key elements: It is based on a 2.4.x linux kernel and it relies on Shorewall for extended firewalling facilities

Brazilfw is a mini-distribution designed for setting up network utility services such as Internet connection sharing, firewalling, or wireless access points. The goal is to make it as quick and easy as possible to set up a Linux system with only a minimal amount of Linux knowledge.
BrlSpeak is a Braille and Speech Mini-Distribution of Linux
that can be installed by a visually impaired person without any external assistance. BrlSpeak comes with a built-in preconfiger for the braille driver, + automated compilation of the braille driver during boot.
BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. The utilities in BusyBox generally have fewer options than their full-featured GNU cousins; however, the options that are included provide the expected functionality and behave very much like their GNU counterparts. BusyBox provides a fairly complete environment for any small or embedded system.
ByzantineOS is a software Internet Appliance with a home entertainment bias. It is based on a networked Linux distribution/bootable system with Mozilla providing access to a range of services and applications. ByzantineOS fits in 32MB (or 48MB) of media and should work on any PC.
CDlinux is a compact distribution. The name is a synonymous of ?Compact Distro Linux?. It is small in size, yet rich in features.
ChainSaw Linux is a GNU/Linux based on the latest stable kernels and is all about video production.
Circle MUDLinux is a three-disk mini-distribution for running the Circle MUD Server that is based on libc5.

Damn Small Linux Not
Damn Small Linux Not is a desktop oriented Linux distribution based on Damn Small Linux. It uses a modern 2.6 Kernel and GTK 2 applications, but like Damn Small Linux, it strives to be compact yet user friendly. It will run well on systems of 300MHz with 64 MB of RAM or greater.
Damn Vulnerable Linux
Damn Vulnerable Linux (DVL) is a Linux-based (modified Damn Small Linux) tool for IT-Security & IT-Anti-Security and Attack & Defense. It was initiated for training tasks during university lessons by the IITAC (International Institute for Training, Assessment, and Certification) and S²e - Secure Software Engineering in cooperation with the French Reverse Engineering Team.

freepia is a small GNU/Linux distribution designed to run on Via Epia-M Mainboards. It currently runs on the M-9000 and M-10000 (ezra and nehemiah cpu) but with some modifications like kernel and X11 modules it should run on others too. The main motivation behind this project is to build a full featured, low noise media box to play movies/mp3s/images etc.
GENDIST creates a makefile-based build-system for your distribution. It helps you to automate the following three tasks: maintain your root-filesystem, maintain your "cd-filesystem", and package everything on a media. GENDIST is similar to BYLD, but it is makefile-based and modular, therefore it is much easier to create your distribution from source.
Gibraltar is a firewall and router package, based on Debian/GNU Linux, which perfectly meets all individual requirements for a state-of-the-art firewall. Independent of the kind of Internet connection (dedicated line, ADSL, dial-up connection), Gibraltar provides for secure connections.
