Distros

Nitrux is a desktop Linux distribution built from Debian, but with an immutable base system, the OpenRC init system, and without any traditional Debian package management tools. It uses the Calamares system installer and includes the Hyprland window manager, Hypr utilities, the greetd+QtGreet login manager, and the Waybar Wayland bar. Nitrux emphasizes the use of AppBox to manage end-user software and it also supports AppImage and Flatpak package formats.

Nobara Project is a modified version of Fedora Linux with user-friendly fixes added to it. The distribution comes with certain features that do not ship with the regular Fedora, such as WINE dependencies, OBS Studio, 3rd party codec packages for GStreamer, NVIDIA drivers, and some package fixes. Nobara aims to fix most of those issues and offer a better gaming, streaming and content creation experience out of the box. The project's official release comes with a custom-themed GNOME desktop, but it also offers separate editions with standard GNOME and KDE desktops.

Noid Linux is a Void-based minimalist Linux distribution with Xfce as the preferred desktop. It includes a long-term supported Linux kernel, the Calamares system installer, the Brave web browser, support for Flatpak packages, and a custom Welcome screen. The project also provides its own repository for Void's XBPS packages with additional software.

NuTyX is a French Linux distribution (with multi-language support) built from Linux From Scratch and Beyond Linux From Scratch, with a custom package manager called "cards". The package manager can install individual binary packages, a group of related binary packages (e.g. desktop packages, such as KDE or Xfce), and compile source packages from "ports". The distribution is designed for intermediate and advanced Linux users.

Nyarch Linux is an Arch-based, rolling-release Linux distribution designed for "weebs", or non-Japanese persons interested in anime, manga, cosplay and other aspects of the Japanese culture. Some of the distribution's custom features include "Catgirl Downloader" which downloads random pictures of cute catgirls, "Nyarch Assistant", a digital companion which helps with a range of computing and real-life tasks, "Material UwU" which serves as a desktop wallpaper and theme chooser, and "Nyarch Customize", a tool to facilitate desktop layout customisations and animations. Besides the standard release, the project also provides a special variant with pre-configured proprietary NVIDIA display drivers; both come with the GNOME desktop.

Obarun is an Arch-based Linux distribution featuring the S6 init software in place of systemd. It provides a live disc featuring the JWM graphical interface. Utilities, such as pacopts, are included for working with Arch's repositories, including the Arch User Repository (AUR).

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".

OmniOS is an open-source operating system for servers, with support for many popular Solaris and OpenSolaris technologies, such as the ZFS file system, bhyve hypervisor, Dtrace (a dynamic tracing framework for troubleshooting kernel and application problems), kernel-based virtual machine, and Linux zone. It is based on Illumos, a free software implementation of the Solaris kernel.
