Guix Days 2024 and FOSDEM recap

Steve George — 2024年02月10日

Guix contributors and users got together in Brussels to explore Guix's status, chat about new ideas and spend some time together enjoying Belgian beer! Here's a recap of what was discussed.

Day 1

The first day kicked off with an update on the project's health, given by Efraim Flashner representing the project's Maintainer collective. Efraim relayed that the project is doing well, with lots of exciting new features coming into the archive and new users taking part. It was really cool listening to all the new capabilities - thank-you to all our volunteer contributors who are making Guix better! Efraim noted that the introduction of Teams has improved collaboration - equally, that there's plenty of areas we can improve. For example, concern remains over the "bus factor" in key areas like infrastructure. There's also a desire to release more often as this provides an updated installer and lets us talk about new capabilities.

Christopher Baines gave a general talk about the QA infrastructure and the ongoing work to develop automated builds. Chris showed a diagram of the way the services interact which shows how complex it is. Increasing automation is very valuable for users and contributors, as it removes tedious and unpleasant drudgery!

Then, Julien Lepiller, representing the Guix Foundation, told us about the work it does. Julien also brought some great stickers! The Guix Foundation is a non-profit association that can receive donations, host activities and support the Guix project. Did you know that it's simple and easy to join? Anyone can do so by simply filling in the form and paying the 10 Euro membership fee. Contact the Guix Foundation if you'd like to know more.

The rest of the day was taken up with small groups discussing topics:

• Goblins, Hoot and Guix: Christine Lemmer-Webber gave an introduction to the Spritely Institute's mission to create decentralized networks and community infrastructure that respects user freedom and security. There was a lot of interesting discussion about how the network capabilities could be used in Guix, for example enabling distributed build infrastructure.

• Infrastructure: There was a working session on how the projects infrastructure works and can be improved. Christopher Baines has been putting lots of effort into the QA and build infrastructure.

• Guix Home: Gábor Boskovits coordinated a session on Guix Home. It was exciting to think about how Guix Home introduces the "Guix way" in a completely different way from packages. This could introduce a whole new audience to the project. There was interest in improving the overall experience so it can be used with other distributions (e.g. Fedora, Arch Linux, Debian and Ubuntu).

• Release management: Julien Lepiller led us through a discussion of release management, explaining the ways that all the parts fit together. The most important part that has to be done is testing the installation image which is a manual process.

Day 2

The second day's sessions:

• Funding: A big group discussed funding for the project. Funding is important because it determines many aspects of what the group can achieve. Guix is a global project so there are pools of money in the United States and Europe (France). Andreas Enge and Julien Lepiller represented the group that handle finance, giving answers on the practical elements. Listening to their description of this difficult and involved work, I was struck how grateful we all are that they're willing to do it!

• Governance: Guix is a living project that continues to grow and evolve. The governance discussion concerned how the project continues to chart a clear direction, make good decisions and bring both current and new users on the journey. There was reflection on the need for accountability and quick decision making, without onerous bureaurcacy, while also acknowledging that everyone is a volunteer. There was a lot of interest in how groups can join together, perhaps using approaches like Sociocracy.

  Simon Tournier has been working on an RFC process, which the project will use to discuss major changes and make decisions. Further discussion is taking place on the development mailing-list if you'd like to take part.

• Alternative Architectures: The Guix team continues to work on alternative architectures. Efraim had his 32-bit PowerPC (Powerbook G4) with him, and there's continued work on PowerPC64, ARM64 and RISC-V 64. The big goal is a complete source bootscrap across all architectures.

• Hurd: Janneke Nieuwenhuizen led a discussion around GNU Hurd, which is a microkernel-based architecture. Activity has increased in the last couple of years, and there's support for SMP and 64-bit (x86) is work in progress. There's lots of ideas and excitement about getting Guix to work on Hurd.

• Guix CLI improvements: Jonathan coordinated a discussion about the state of the Guix CLI. A consistent, self-explaining and intuitive experience is important for our users. There are 39 top-level commands, that cover all the functionality from package management through to environment and system creation! Various improvements were discussed, such as making extensions available and improving documentation about the REPL work-flow.

FOSDEM 2024 videos

Guix Days 2024 took place just before FOSDEM 2024. FOSDEM was a fantastic two days of interesting talks and conversations. If you'd like to watch the GUIX-related talks the videos are being put online:

• Making reproducible and publishable large-scale HPC experiments by Philippe Swartvagher.

• Scheme in the Browser with Guile Hoot and WebAssembly by Robin Templeton.

• RISC-V Bootstrapping in Guix and Live-Bootstrap by Ekaitz Zarraga.

• Self-hosting and autonomy using guix-forge by Arun Isaac.

• Spritely, Guile, Guix: a unified vision for user security by Christine Lemmer-Webber.

• Supporting architecture psABIs with GNU Guix by Efraim Flashner.
