The “Virtual Richard M. Stallman” Tool: How Much Non-Free Software Is Really on Your Linux System?

Most Linux users pride themselves on running only free software. We champion open-source principles, extol the virtues of transparency, and celebrate the freedom that Linux provides. Yet if we’re being honest with ourselves, how many of us can truly claim our systems are entirely free of proprietary components?

The reality is that modern Linux workstations often depend on at least some non-free elements to meet user expectations. Whether it’s GPU drivers for optimal graphics performance, firmware for hardware compatibility, or multimedia codecs for playing common media formats, proprietary software has become a practical necessity for many Linux users.

But here’s the uncomfortable question: Do you actually know which non-free software you’re running? Many users would be surprised to discover just how much proprietary code exists on their supposedly “pure” Linux systems.

This is where an intriguing little tool called vrms (short for “virtual Richard M. Stallman”) comes into play, offering users unprecedented visibility into their software ecosystem.

What Exactly Is vrms?

Originally developed within the Debian community, vrms is a diagnostic utility that scans your installed packages and identifies those that don’t comply with the Debian Free Software Guidelines (DFSG). Rather than enforcing any particular ideology or automatically removing software, vrms takes an educational approach—it simply reports back to you, allowing you to make informed decisions about your system.

The tool works by examining Debian’s package metadata, which categorizes software into different sections: packages in the “main” archive are considered free, while those in “non-free” or “contrib” repositories fall outside Debian’s definition of free software. After installation, running vrms provides a clear breakdown of what’s on your system.

For Debian and its derivatives, the functionality is available through the check-dfsg-status tool (accessible via the transitional vrms package). The output is straightforward and informative, giving users a concrete understanding of their software composition.

Bringing vrms to RPM-Based Systems

The concept proved so valuable that the community adapted it for RPM-based distributions through vrms-rpm, a project maintained by volunteers that brings Stallman’s virtual oversight to Fedora, RHEL, openSUSE, and related systems.

Since RPM distributions don’t use Debian’s DFSG framework, vrms-rpm takes a different approach. It analyzes RPM license tags and compares them against configurable allowlists—either Fedora’s approved licenses or SPDX-based definitions. Despite these implementation differences, the core mission remains identical: transparency about what software meets (or doesn’t meet) the distribution’s free software criteria.

Both tools share important characteristics: they rely entirely on package metadata accuracy, make no system modifications, and function purely as reporting and auditing utilities. They’re educational tools, not enforcement mechanisms.

The Arch Linux Philosophy: A Different Approach

When it comes to Arch Linux and its derivatives, the story takes an interesting turn. Unlike Debian and Fedora, Arch deliberately chooses not to provide an official equivalent to vrms or DFSG-style compliance checks. And this isn’t an oversight—it’s a conscious reflection of Arch’s fundamentally different distribution philosophy.

Arch Linux explicitly does not classify packages as “free” or “non-free” at the policy level. The distribution intentionally avoids making value judgments about software freedom, leaving such decisions entirely to users. This hands-off approach aligns perfectly with Arch’s broader philosophy of user empowerment and minimalism.

The result? Arch has become one of the most beloved, widely adopted, and respected distributions in the Linux ecosystem—despite (or perhaps because of) its refusal to impose ideological purity tests on its software repositories.

This raises an interesting question: Does the absence of built-in free software auditing tools make Arch less principled, or does it represent a more mature, user-centric approach that trusts individuals to make their own ethical decisions about their software?

Why This Matters in 2025

As Linux continues its march toward mainstream adoption, tools like vrms serve an increasingly important purpose. They help users understand the practical realities of modern computing while honoring the philosophical foundations of the free software movement.

The tension between ideological purity and practical functionality isn’t going away. GPU manufacturers still primarily provide proprietary drivers. Some hardware requires proprietary firmware to function. Certain media formats remain encumbered by patents. These realities mean that even the most freedom-conscious users often find themselves making compromises.

Tools like vrms don’t judge these compromises—they simply illuminate them, empowering users with knowledge about their own systems.

How to Get Started

For Debian/Ubuntu users:
bash
sudo apt install vrms
vrms

For Fedora/RHEL users:
bash
sudo dnf install vrms-rpm
vrms-rpm

For Arch users, while no official tool exists, the Arch Wiki provides guidance on manually auditing package licenses, and community-maintained AUR packages occasionally emerge to fill this gap.

The Bigger Picture

The existence and evolution of tools like vrms reflect the ongoing maturation of the Linux ecosystem. They represent a bridge between the idealistic foundations of the free software movement and the pragmatic realities of modern computing.

Whether you’re a free software purist, a practical user who accepts some compromises, or somewhere in between, understanding what’s actually running on your system is valuable knowledge. In an age of increasing concern about privacy, surveillance, and digital rights, this kind of transparency matters more than ever.

After all, you can’t make informed decisions about your software freedom if you don’t know what software you’re actually running.
