JayOS is a live CD Linux distribution intended for use as a more secure mobile environment. It uses GNU makefiles and Bash shell scripts to automate the building of a complete Linux distribution from source. The result is a turnkey solution for creating a compact, highly-customizable OS. JayOS includes many standard network security and filesystem tools, a full-blown development environment, and many programming tools and libraries including GCC, GDB, DDD, Perl, GTK+, Tcl/Tk, PHP, Ruby, Python, Qt, and Glade. It runs well on commodity hardware, and can be configured to run entirely from memory. In-RAM filesystem encryption with plausible deniability provides a more secure mobile workstation. It is based on Linux From Scratch.
IronBox Linux is a Linux distribution based on Linux From Scratch and designed for usage in high security server environments. Its main goal is to ensure a stable and secure deploy where patching and system upgrades do not depend on security bugs, but on the task team schedules and the needed features of the system or the software it runs.
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.
Partimage Is Not Ghost (PING) is a live Linux ISO based on LFS (Linux From Scratch). It can be burnt on a CD and booted, or integrated in a PXE/RIS environment. Several tools that make it the perfect choice for easily backing up and restoring whole partitions are included. It supports backups to and from SMB shares, backup of BIOS data, the ability to blank the local admin's password, creation of bootable restoration DVDs, the ability to partition and format a disk before installing Windows, and more.
Nightwing allows the creation of quickly deployed wireless networks without the need to make complicated configurations. With the implementation of a Mesh technology called B.A.T.M.A.N, Nightwing allows the extension of wireless networks with a simple way of adding devices that works with minimal human intervention. It has public and private connection interfaces, and the ability to filter content using OpenDNS. It is designed with security in mind, and has low hardware requirements.
Mandriva is an RPM-based Linux distribtion. It excels at usability and simplicity, features thoroughly preconfigured KDE and GNOME desktops, and includes cool tools like supermount (transparent access to removable media) and DiskDrake (a full-featured graphical hard-drive partitioner). Unlike former versions, Mandriva is not a tuned-up Red Hat, but a very mature Linux distribution on its own. Mandriva is published by a company, but is a completely open and transparent free-software project.
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.
stresslinux is a minimal Linux distribution that runs from a bootable CDROM or via PXE. It makes use of some utitlities such as stress, cpuburn, hddtemp, lm_sensors, etc. It is dedicated to users who want to test their system(s) entirely on high load and monitor the health of these systems.
