Yes but that derivation also depends on other derivations, for instance qemu-minimal and if I try: --8<---------------cut here---------------start------------->8--- mathieu@berlin ~$ guix build qemu-minimal ... /gnu/store/lwv2pl0m6dkf6bkzip755w5p71g5akq4-qemu-minimal-7.1.0 --8<---------------cut here---------------end--------------->8--- and then, from my machine. --8<---------------cut here---------------start------------->8--- curl https://ci.guix.gnu.org/lwv2pl0m6dkf6bkzip755w5p71g5akq4.narinfo We're baking it: /lwv2pl0m6dkf6bkzip755w5p71g5akq4.narinfo --8<---------------cut here---------------end--------------->8--- wget exhibits the same behaviour and returns 404. So any build that requires a heavy substitute, heavier than the cache bypass threshold at least, will fail on the workers, as it would fail locally. That's not really a surprise as baking substitutes takes time and there is a time window between the moment Cuirass triggers NAR baking and the moment the NAR is baked, where every user will get a 404.
