Updated Linux Distributions

Netrunner is a Debian-based distribution featuring a highly customised KDE desktop with extra applications, multimedia codecs, Flash and Java plugins, and a unique look and feel. The modifications are designed to enhance the user-friendliness of the desktop environment while still preserving the freedom to tweak. A separate "Rolling" edition, based on Manjaro Linux, was launched in 2014, was discontinued, re-launched in 2017, and discontinued again in 2019.

Puppy Linux is yet another Linux distribution. What's different here is that Puppy is extraordinarily small, yet quite full-featured. Puppy boots into a ramdisk and, unlike live CD distributions that have to keep pulling stuff off the CD, it loads into RAM. This means that all applications start in the blink of an eye and respond to user input instantly. Puppy Linux has the ability to boot off a flash card or any USB memory device, CDROM, Zip disk or LS/120/240 Superdisk, floppy disks, internal hard drive. It can even use a multisession formatted CD-RW/DVD-RW to save everything back to the CD/DVD with no hard drive required at all.

StartOS is a Debian-based Linux distribution optimised for personal servers. It facilitates the discovery, installation, network configuration, service configuration, data backup, dependency management and health monitoring of self-hosted software services. After installation, the distribution boots into a Firefox browser with several services pre-installed and others, including various Bitcoin, communication, data and artificial intelligence services available from the project's online marketplace. The server can be accessed locally or from anywhere in the world via Tor network's Onion service. The distribution is developed by Start9 Labs, Inc.

Alien-OS is a German Linux distribution based on Debian's latest "Stable" release, with components borrowed from MX Linux.

Arch Linux is an independently developed, x86_64-optimised Linux distribution targeted at competent Linux users. It uses 'pacman', its home-grown package manager, to provide updates to the latest software applications with full dependency tracking. Operating on a rolling release system, Arch can be installed from a CD image or via an FTP server. The default install provides a solid base that enables users to create a custom installation. In addition, the Arch Build System (ABS) provides a way to easily build new packages, modify the configuration of stock packages, and share these packages with other users via the Arch Linux user repository.

ZimaOS is an independently-developed, Linux-based operating system for personal servers and network-attached storage (NAS) devices. It features system-level support for remote access, RAID configuration, over-the-air (OTA) updates, and a browser-based user interface for managing the server. It is developed in China by IceWhale Technology Limited, which also produces and sells specialist storage hardware devices called "ZimaCube". Besides ZimaOS which is a complete, standalone operating system, the company also produces CasaOS, a lightweight software layer that can be installed on top of an existing Linux installation in order to turn it into a personal server or a NAS.

EznixOS is a live Linux distribution based on Debian's "Stable" branch. It offers three editions of the product, containing a customised Xfce desktop (with extra software), a non-customised Xfce desktop, and a non-customised KDE Plasma desktop. It can be installed to a hard disk using the standard Calamares system installer. Besides the three Debian spins, the project also develops and distributes files, scripts and documentation for building customised live Debian images.

Recalbox is a dedicated operating system for running video games on emulated retro and console platforms. Recalbox can also be used to run the Kodi media centre. The distribution's interface is primarily navigated with a console game controller, though keyboard support is available for many functions.

MidnightBSD is a FreeBSD-derived operating system. A critical goal of the project is to create an easy-to-use desktop environment with graphical ports management, and system configuration using GNUstep. The vast majority of the operating system will maintain a BSD license. MidnightBSD was forked from FreeBSD 6.1 beta.

Dr.Parted Live is a bootable GNU/Linux distribution based on Debian's "Testing" branch. It is a live image featuring a lightweight Openbox window manager and useful applications for disc partitioning as well as data backup, restore and recovery.

Kiro is an Arch Linux-based distribution with the goal of being an intuitive and customisable ISO image builder. It provides a simple way to build a custom Arch-based installation medium with a choice of packages, settings and scripts. Kiro uses the Xfce desktops, includes the Calamares system installer, and has a modular structure.

ObsidianOS is a set of Linux distribution based primarily on Arch Linux. Its main feature is an A/B partition style (as used by Android or Chrome OS) so if an update causes some issues, it is possible to reboot into the first partition and restore the second one. It uses the ext4 filesystem exclusively. ObsidianOS offers three variants of the product - "Base", "KDE Plasma" and "COSMIC".

CuerdOS is a Debian-based GNU/Linux distribution with focus on stability, efficiency and performance. It comes with a series of optimisations, such as performance and memory consumption improvements. These optimisations are achieved through kernel patching and the Ananicy daemon, the latter of which manages input/output and CPU priorities. The distribution's "Standard" product uses Wayland's Sway compositor by default, but separate "Legacy" and "Community" builds with Budgie, Cinnamon, LXQt, MATE and Xfce desktops are also available.

AerynOS is an independently-developed, rolling-release Linux distribution designed for general desktop use. Its main features include the GNOME desktop, a custom package manager called "moss", atomic updates with rollback options, a package build system called "boulder", and smart boot management with complex EFI configuration through a utility called "blsforme".

Calam Arch Installer is an Arch-based Linux distribution created to facilitate the installation of an Arch Linux system to a hard disk. It is also a full-featured live Linux system with Xfce as the preferred desktop. The Calamares system installer offers a choice of several popular desktop environments and window managers, including Budgie, Cinnamon, Deepin, GNOME, i3, KDE Plasma, MATE, Openbox and Xfce. The distribution also offers support for both BIOS and UEFI boot, as well as hard disk encryption with LUKS.

Security Onion is a specialist, security-oriented Linux distribution based on Oracle Linux. It is a free and open platform for threat hunting, enterprise security monitoring and log management. It includes custom interfaces for alerting, dashboards, hunting, PCAP, detections and case management. It also includes other tools, such as osquery (a tool for exploring and monitoring operating system data with SQL queries), CyberChef (a web application for encryption, encoding, compression and data analysis), Elasticsearch (a data search engine), Logstash (a data collection and processing engine), Kibana (a data visualization plugin for Elasticsearch), Suricata (an intrusion detection and prevention system) and Zeek (a software network analysis framework).

MocaccinoOS is an independently-developed Linux distribution that has its origins in source-based Gentoo Linux and Sabayon Linux. It uses a custom-built package manager called "Luet", which acts as a front-end for container-based software. The distribution's main features are minimalism and small footprint, ease of use, native vanilla Linux kernels, and support for most important cloud technologies. MocaccinoOS is offered in several variants, including live images with GNOME, KDE Plasma, MATE and Xfce desktops, as well as command-line-only "Minimal Desktop" edition.

Athena OS is an Arch-derived Linux distribution designed for penetration testing, bug-bounty hunting and InfoSec students. The distribution provides a way to connect directly to some of the e-learning hacking resources, such as Hack The Box, Offensive Security, PWNX and InfoSec certifications, and it provides integration with the Hack The Box hacking platform and connections to InfoSec communities. Athena OS also introduces InfoSec roles (e.g. penetration tester or open-source intelligence specialist) based on user preferences, so the user's system is populated with relevant tools only.
