Is the hydra/front-end hardware going to be upgraded? Is bayfront/cuirass intended to replace hydra? The bayfront hardware described here ... https://www.gnu.org/software/guix/news/growing-our-build-farm.html ... seems weak to me. Is there a plan to scale it up and make it redundant? A reliable, resourced, managed, "nightly Guix build" should pay big dividends for the project. But, from reading the lists, I get the impression that such a thing does not exist. Is that correct? Do we know what would be needed to achieve a complete nightly build? TIA - George
