Updated Linux Distributions

GhostBSD is a user-friendly desktop operating system based on FreeBSD. Its default desktop is MATE, but a separate community edition with Xfce is available too. It also features a selection of commonly used software, a rolling-release development model, and a bootable live image with an intuitive graphical system installer.

AUSTRUMI (Austrum Latvijas Linukss) is a bootable live Linux distribution based on Slackware Linux. It requires limited system resources and can run on any Intel-compatible system with a CD-ROM installed. The entire operating system and all of the applications run from RAM, making AUSTRUMI a fast system and allowing the boot medium to be removed after the operating system starts.

RebeccaBlackOS is a Debian-based live distribution which can be used to run Wayland desktop sessions. RebeccaBlackOS can run a number of popular open source desktop environments on top of a Wayland graphical session. The distribution was (and remains) one of the only Linux distributions to run a Wayland session from live media. The distribution is available in 32-bit and 64-bit builds for the x86 architecture.

Network Security Toolkit (NST) is a bootable live disc based on the Fedora distribution. The toolkit was designed to provide easy access to best-of-breed open source network security applications and should run on most x86 platforms. The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of open source network security tools. What we find rather fascinating with NST is that we can transform most x86_64 systems into a system designed for network traffic analysis, intrusion detection, network packet generation, wireless network monitoring, a virtual system service server, or a sophisticated network/host scanner.

CachyOS is a Linux distribution based on Arch Linux. It focuses on speed and security optimisations - the default Linux kernel is heavily optimised using the BORE (Burst-Oriented Response Enhancer) scheduler, while the desktop packages are compiled with LTO, x86-64-v3 and x86-64-v4 optimization, security flags and performance improvements. The available desktop environments and window managers include KDE, GNOME, Xfce, CuteFish, i3wm, Wayfire, LXQt, OpenBox, Cinnamon, UKUI, LXDE, MATE, Budgie, Qtile, Hyprland and Sway. CachyOS also ships with both graphical and command-line installers and provides a Firefox-based browser (called Cachy-Browser) with some security enhancements and performance optimisations.

Endless OS is a Linux-based operating system which provides a simplified and streamlined user experience using a customized desktop environment forked from GNOME 3. Rather than using a traditional Linux package management system, Endless OS uses a read-only root filesystem managed by OSTree with application bundles overlaid on top.

Kali Linux (formerly known as BackTrack) is a Debian-based distribution with a collection of security and forensics tools. It features timely security updates, support for the ARM architecture, a choice of four popular desktop environments, and seamless upgrades to newer versions.

ReactOS is a free and open-source operating system based on the best design principles found in the Windows NT architecture. Written completely from scratch, ReactOS is not a Linux-based system and it shares none of the UNIX architecture. The main goal of the ReactOS project is to provide an operating system which is binary compatible with Windows. This will allow Windows applications and drivers to run as they would on a Windows system. Additionally, the look and feel of the Windows operating system is used, such that people accustomed to the familiar user interface of Windows would find using ReactOS straightforward. The ultimate goal of ReactOS is to allow people to use it as an alternative to Windows without the need to change software they are used to.

Pentoo is a Gentoo-based Linux live CD with a selection of applications and tools designed to perform penetration testing.

Karoshi is a free and open source school server operating system developed by the Linux Schools project and based on Ubuntu. Karoshi provides a simple graphical interface that allows for quick installation, setup and maintenance of a network.

EuroLinux is an enterprise-class Linux distribution made and supported by the EuroLinux company, built mostly from code of Red Hat Enterprise Linux. The origin of the system ensures compatibility with most popular enterprise Linux distributions including Red Hat Enterprise Linux, Oracle Linux, and CentOS. While primarily geared toward server workloads, EuroLinux can also be used for desktop computing or any environment where long-term stability and support are demanded.

MX Linux, a desktop-oriented Linux distribution based on Debian's "Stable" branch, is a cooperative venture between the antiX and former MEPIS Linux communities. Using Xfce as the default desktop (with separate KDE Plasma and Fluxbox editions also available), it is a mid-weight operating system designed to combine an elegant and efficient desktop with simple configuration, high stability, solid performance and medium-sized footprint.

LinuxConsole is an independently developed Linux live CD with different editions designed for desktops, servers, gaming consoles, and old computers. Its primary characteristics are easy installation, extensive choice of software in the form of modules, and excellent hardware detection.

Haiku is an open-source operating system, currently in development, that specifically targets personal computing. Inspired by the Be Operating System (BeOS), Haiku aims to become a fast, efficient, simple to use, easy to learn and yet very powerful system for computer users of all levels. The key highlights that distinguish Haiku from other operating systems include: specific focus on personal computing, custom kernel designed for responsiveness, fully threaded design for great efficiency with multi-processor/core CPUs, rich object-oriented API for faster development, database-like file system (BFS) with support for indexed metadata, and unified, cohesive interface.

Rescuezilla is a specialist Ubuntu-based distribution designed for system rescue tasks, including backups and system restoration. It was forked from the "Redo Backup & Rescue" project which was abandoned in 2012. Like its predecessor, it allows a "bare-metal restore" after any hardware failure directly from the live image. Some of the features include: works directly from the live CD/USB image; works with Linux, macOS and Windows; automatically searches a local area network for drives to backup to or restore from; recovers lost or deleted data files; includes configuration tools for managing disk and drives. Rescuezilla uses a simplified LXDE user interface.

IPFire is a Linux distribution that focuses on easy setup, good handling and high level of security. It is operated via an intuitive web-based interface which offers many configuration options for beginning and experienced system administrators. IPFire is maintained by developers who are concerned about security and who update the product regularly to keep it secure. IPFire ships with a custom package manager called Pakfire and the system can be expanded with various add-ons.

Thinstation is a modern thin client that does work on its own for basic operations like web browsing, managing removable media and printers, but rely on servers for major applications as well as administration of the clients. The clients may be diskless or boot from local media. Thinstation works as a client using X, ICA, RDP, SSH, NX, telnet, tn5250 and other protocols and works on standard PC hardware.

Live Raizo is a live distribution based on Debian to experiment with system administration on simulated networks and real devices. It contains simulators of networks and systems (GNS3, QEmu, Docker, VPCS) and also Debian virtual machines already integrated into GNS3. Live Raizo also includes tools to interact with real devices: minicom, Putty, Wireshark, as well as DHCP, DNS, FTP, TFTP and SSH servers. The project can optionally be installed to a hard drive.

Rocky Linux is a community enterprise operating system designed to be 100% bug-for-bug compatible with Red Hat Enterprise Linux. It is available for the x86_64 and AArch64 processor architectures.

Daphile is a minimal operating system for running a digital audio player on a headless computer. The operating system and media manager can be controlled remotely using a web-based interface.
