CalamaroOS is a desktop Linux distribution that builds on Gentoo Stage 3 with systemd and aims to make Gentoo easier to install and use.
It provides a Calamares graphical installer, official Gentoo binary packages, source compilation where needed, Flatpak integration, and a choice of KDE Plasma, LXQt, MATE, and Xfce editions. The distribution targets 64-bit systems and offers a quicker route into a Gentoo-based desktop without requiring users to perform a traditional manual Gentoo installation.

What's a Linux distribution ("distro")? |
| A distro provides the user with a desktop environment, preloaded applications, and ways to update and maintain the system. Each distro makes different choices, deciding which open source projects to install and provides custom written programs. They can have different philosophies. Some distros are intended for desktop computers, some for servers without a graphical interface, and others for special uses. Because Linux is an open source operating system, combinations of software vary between Linux distros. |
