GNU/Linux Distros
Free GNU/Linux system distributions (or “distros”) only include and only propose free software. They reject non-free applications, non-free programming platforms, non-free drivers, non-free firmware “blobs”, and any other non-free software and documentation. If they discover that by mistake some had been included, they remove it.
Free GNU/Linux Distros
We recommend that you use a free GNU/Linux system distribution, one that does
not include proprietary software at all. That way you can be sure that you are
not installing any non-free programs. Here is our list of such distros:
Free GNU/Linux distributions.
All of these existing distros could use more development help. Thus, if you want to make an effective contribution to free GNU/Linux distributions, we suggest that you join the development of an existing free distro rather that starting a new free distro.
Free Distro Guidelines
Here is the list of problems that can prevent a distro from being
considered entirely free:
Guidelines for free system distributions.
Common Distros
Many common and well-known GNU/Linux software distributions don't meet
our guidelines. You can read about their problems here:
Why we can't endorse many well-known GNU/Linux distros.
We appeal to the developers of these distros to remove the non-free parts and thus make them entirely free software.
