While we are talking infrastructure, a short digression on the current situation. The Berlin build farm is providing substitutes for all branches and development branches. It is providing system images that are made available on the Guix website, on Gnome Boxes and probably elsewhere. It is giving a frequent status on the system tests. It is also checking that all our sources are available and feeding the Disarchive database. When this build farm is experiencing troubles, all those important services are suspended or limited. As you may know, Berlin is also experiencing storage issues that will soon be really problematic. Having Bordeaux as another build farm monopolizing resources and requiring new hardware while maintaining Berlin is already a huge burden seems untenable to me. I personally think that having Bordeaux as an alternative build farm, running alternative software is a wrong direction for the project. I would personally prefer to put a stop to that situation. We should clearly host some services such as the Guix website on Berlin & Bordeaux to bring some redundancy. However, as far as substitutes building is concerned, redundancy is premature when maintaining a single system, with our limited human and hardware resources, proves to be so complex. What do other people think? Thanks, Mathieu
