I have been using the Guix System for a long time and I am willing to improve the system. For example there is still much work needed to get the complete Guix System running on a Talos II or the big endian PowerPC notebook or its 2025 desktop version. I have added the The FSF's free software hackathon[1] to my calendar and I am willing to do some work to get the guix system running on those systems.
