Introduction

ROSA is a flexible, user-friendly Linux distribution developed by ROSA Laboratory, a Russian company with a strong focus on open-source solutions. Since its inception, ROSA has aimed to combine stability, performance, and an intuitive desktop experience. The project offers multiple editions tailored to home users, enterprises, educational institutions, and specialized environments. This article delves into what ROSA is, how it works, its primary orientations, and some intriguing curiosities that set it apart in the vast ecosystem of Linux distributions.

What Is ROSA?

History and Origins

ROSA was born in 2010 as a fork of the Mandriva Linux distribution, following Mandriva’s gradual decline. A group of former Mandriva developers and enthusiasts joined forces to create ROSA Lab, ensuring continuity for the Mandriva codebase and community spirit. Over the years, ROSA evolved significantly, adding custom tools, modern desktop environments, and enterprise-grade features.

Development and Community

The ROSA ecosystem comprises professional developers, community contributors, and corporate partners. The project is guided by the following principles:

• Open Collaboration: Public repositories and forums encourage contributions.
• Quality Assurance: Rigorous testing in both community (Beta) and stable (LTS) branches.
• Localization: Strong support for multiple languages, especially Russian and English.

How ROSA Works

System Architecture

At its core, ROSA leverages the Linux kernel, enriched with specialized drivers and modules. The distribution is structured around:

• Custom Kernel Builds: Optimized for hardware compatibility and performance.
• Modular Packages: RPM-based packages organized in repositories for easy maintenance.
• Layered Configuration: Simplified system administration via graphical tools.

Kernel and Core Components

• Linux Kernel: Regularly updated long-term support (LTS) versions.
• GNU Toolchain: Core utilities like glibc, Bash, GCC, and systemd.
• System Services: systemd for init, Polkit for privileges, and D-Bus for IPC.

Desktop Environments

ROSA offers polished desktop experiences with two main flavors:

• KDE Plasma: Known as ROSA Desktop Fresh, featuring a modern, customizable interface.
• GNOME XFCE: Available in some community spins for lightweight performance.

Package Management

ROSA uses URPMI, an RPM-based package manager inherited from Mandriva. Key features include:

• Dependency Resolution: Automatic handling of package dependencies.
• Multiple Repositories: Core, Updates, Backports, and third-party sources.
• Graphical Tools: rpmdrake for browsing, installing, and removing packages.

Release Models

ROSA follows a dual release strategy:

1. Fresh Edition: A rolling-release-like model for enthusiasts seeking the latest software.
2. Enterprise/Starter Edition: A Long-Term Support (LTS) branch with stable updates and extended maintenance.

Orientation and Use Cases

Home and Office Users

For everyday computing, ROSA provides:

• Preinstalled Applications: Office suites, browsers, multimedia codecs.
• User-Friendly Installers: Graphical wizard for an easy setup.
• Hardware Support: Out-of-the-box drivers for printers, Wi-Fi, and graphics cards.

Enterprise Deployments

The Enterprise/Starter editions are tailored for corporate environments:

• Centralized Management: Tools for network-wide deployment and updates.
• Security: SELinux integration, encrypted file systems, and advanced firewall configuration.
• Support Options: Commercial support contracts with ROSA Lab.

Educational and Public Sector

ROSA is popular in educational institutions and government agencies, thanks to:

• Localization: Full Russian, English, and other language interfaces.
• Cost Efficiency: Open-source licensing reduces software expenses.
• Training Materials: Custom documentation and tutorials provided by ROSA Lab.

Specialized Editions

Beyond mainstream releases, ROSA periodically launches:

• Server Editions: Optimized for web, database, and virtualization workloads.
• Multimedia Editions: Enhanced audio/video production tools.
• Embedded Solutions: Lightweight spins for industrial controllers.

Features and Advantages

• Integrated Software Center: One-stop shop for discovering and managing applications.
• Visual System Configuration: Centralized control panel for hardware, network, and user management.
• Continuous Innovation: New features such as ROSA Media Player and ROSA Imaging Suite.
• Security Framework: Mandatory access controls, encryption wizards, and regular security patches.
• Community Support: Active forums, knowledge base, and IRC channels.

Curiosities

• Meaning of the Name: “ROSA” stands for “ROSA-Soft” historically, but today it’s simply a brand name evoking a “rose” as a symbol of elegance and robustness.
• Mandriva Legacy: Some ROSA developers originally worked on Mandriva Linux, maintaining compatibility with older Mandriva packages.
• Custom Tools: DrakFireWall, DrakBackup, and DrakConf are GUI utilities inherited from Mandriva and extended by ROSA.
• Rolling-Release Experiments: The Fresh edition sometimes features upstream packages packaged within weeks of their official release.
• Local Festivals: The ROSA Lab team regularly hosts ROSA Day events in Moscow, offering workshops and user meetups.
• Global Reach: Though based in Russia, ROSA has community mirrors in Europe, Asia, and the Americas.
