Frugalware is a general-purpose Linux distribution designed for intermediate users who are not afraid of text mode. "The Frugalware Philosophy" is about simplicity, multimedia, and design. The authors try to make Frugalware as simple as possible while not forgetting to keep it comfortable. Frugalware uses Judd Vinet's pacman package manager.
ROPE is an open-ended iptables match module that allows rules to be written using a simple but powerful scripting language. It is designed for controlling complex high-level protocols that cannot be blocked using traditional criteria based on port numbers (etc.). Criteria can include tests on any field of the IP, UDP, or TCP headers as well as the packet data payload.
Plash is a sandbox for running GNU/Linux programs with minimum privileges. It is suitable for running both command line and GUI programs. It can dynamically grant Gtk-based GUI applications access rights to individual files that you want to open or edit. This happens transparently through the Open/Save file chooser dialog box, by replacing GtkFileChooserDialog. Plash virtualizes the file namespace and provides per-process/per-sandbox namespaces. It can grant processes read-only or read-write access to specific files and directories, mapped at any point in the filesystem namespace. It does not require modifications to the Linux kernel.
UniPackage is an alternative to distribution-specific packaging systems like dpkg and RPM. UniPackage is a simple system that works on any Linux distribution. UniPackage packages are tar.bz2 archives which contain a self-contained "AppDir" which can be moved anywhere in the filesystem without disturbing the application's installation. In most cases, this packaging does not require changes to the application's code. The issue of dependencies is avoided by bundling all required libraries in the AppDir.
YES Linux is a server appliance for small and medium size networks to quickly and easily build an Internet presence. It completely installs in under 10 minutes and 2 screens. It features a secure Web server, a secure email server with Web-based email, a firewall, spam filtering, WebDAV support, an FTP server, an SSH server, a PostgreSQL database, the Resin J2EE server, Java, Apache Ant, PHP 5, Autonomous Backups, and complete Web-based administration.
Grml is a live system (live CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. It provides automatic hardware detection and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes more than 2 GB of software and documentation on the CD.
Kerrighed is a Single System Image operating system (SSI) for clusters. It offers the view of a unique SMP machine on top of a cluster of standard PCs. The goals are high performance of applications, high availability of the cluster, efficient resource management, high customizability of the operating system, and ease of use. It is implemented as an extension to Linux operating system (a set of Linux modules and a small patch to the kernel).
