Lernstick Exam Environment is a live Linux distribution with a focus on exam situations, usually installed on USB sticks. To provide up-to-date software choice on a solid base, it uses a combination of Debian stable with official and custom backports. Access to local storage media (internal hard drive, other USB storage media) or network access is prohibited per default, but certain network connections (e.g., to network printers or websites) can be allowed in a whitelist.
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.
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.
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.
m23 is a software deployment system for Debian GNU/Linux that allows you to install and administrate hundreds of clients via network. It can partition and format clients and install Debian, (K/X)Ubuntu, Linux Mint, Fedora, OpenSuse, and CentOS operating systems on your virtual and physical clients. Group functions allow the comfortable update and installation of further packages during operation. Mass installation functions simplify your administration chores. m23 has a Web interface. Backup functions are implemented for server and clients.
Puppy Linux is a Linux distribution that is about 100 megabytes, yet it includes a complete set of graphical applications, combined with extensive utility applications. Puppy was created from scratch, file-by-file, optimized for size at every step. Another feature of Puppy Linux is that it can work totally without a hard drive, even allowing you to save data and install extra packages by saving back to the CD or DVD.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
