GNU Guix and the GNU System

GNU Guix (pronounced like "geeks") is a purely functional package manager for the GNU system.

Dependable. In addition to standard package management features, Guix supports transactional upgrades and roll-backs, unprivileged package management, per-user profiles, and garbage collection. Read more...

Hackable. It provides Guile Scheme APIs, including high-level embedded domain-specific languages (EDSLs), to describe how packages are built and composed. Read more...

Liberating. Guix forms the basis of the Guix System Distribution—GNU's advanced GNU/Linux distro—which respects the freedom of computer users. Read more...

Guix is based on the Nix package manager.

As of version 0.8.1, the Guix System Distribution can be installed on an i686 or x86_64 machine. It uses the Linux-Libre kernel and the GNU dmd init system.

Alternately, GNU Guix can be installed as an additional package manager on top of an installed Linux-based system, on i686, x86_64, mips64el, and on armv7.

Its salient package management features are implemented. The distribution provides 1,500+ packages transparently available as pre-built binaries. The Guix System Distribution has some limitations but will please the enthusiastic hacker in you. Join us in improving it!


Guix in its early development stages. Source code for Guix as well as USB installation images of the Guix System Distribution can be found on the GNU ftp server for alpha releases: (via HTTP) and (via FTP).

See the installation instructions from the manual.





The Guix-devel mailing list (archive) is used to discuss Guix, including development and enhancement requests. Until July 2013, the bug-Guix mailing list filled that role.

Use gnu-system-discuss (archive) for discussions about the broader GNU system.

Use guix-sysadmin (private mailing list) to report issues with system administration of Hydra and the build machines.

Use gnu-linux-libre (archive) for discussions about free system distributions.

Commit notifications

Guix-commits receives notifications of commits to the version control repository.


Announcements about Guix and most other GNU software are made on info-gnu (archive).

Security reports

Security reports that should not be made immediately public can be sent directly to the maintainer. If there is no response to an urgent issue, you can escalate to the general security mailing list for advice.

Internet relay chat

Some Guix users and developers hang out on the #guix channel of the Freenode IRC network (logs).

Reporting bugs

Use the bug-Guix (archive) mailing list to report bugs.

Before reporting a bug, please check whether the bug is already in the bug database. See the developer information page for more information on how to manipulate bug reports.

Hardware donations

The build farm of the Guix System Distribution runs on donated hardware and hosting.

As the distribution grows (see the package list), so do the computing and storage needs. We are looking for donations of hardware and optionally hosting for the following kinds of machines (they should be usable with exclusively free software):

Please get in touch with us through the usual channels or using the private alias to discuss any opportunities.

Getting involved

Source code repository

Guix is developed using the Git version control system.

Anonymous checkout: git clone git://

You can also browse the Git repository with your web browser:

Commit notifications can be received on the Guix-commits mailing list.

Contributing new code

Guix is implemented in Scheme, using GNU Guile. You do not need to be a Guile or Scheme expert to use Guix or to contribute packages to the distribution—that is what this talk demonstrated. Information on how to add packages to the distribution can be found in the manual.

Nonetheless, if you want to dive further into Guix, you will find it useful to browse Guile's manual or other introductory material about Scheme. Also, make sure to read the HACKING files for more details on the development setup, as well as the coding and cooperation conventions used in the Guix project.

Non-software contributions

A repository with artwork for use in the operating system, such as the logo, background image of the bootloader, etc., is available at git:// We're always looking for help in this area, so do chime in if you're interested!

Documents, supporting material of previous talks, and auxiliary information useful to hackers and maintainers is available at git://

Development of Guix, and GNU in general, is a volunteer effort, and you can contribute. For information, please read How to help GNU. If you'd like to get involved, it's a good idea to join the mailing lists
