Not a bug! :-) Hydra and Cuirass first go through an “evaluation” step, which consists in producing a list of derivations + meta-data from Guix/GuixSD. Concretely, Hydra runs build-aux/hydra/gnu-system.scm, which returns that list (you can run “make hydra-jobs.scm” to see that result.) As can be seen at the top of gnu-system.scm, the idea is to let Guile’s auto-compilation kick in rather than have an explicit build step. It simplifies gnu-system.scm at the expense of providing messy output; it’s also quite expensive. I’m open to a brainstorming session on this. I’m not sure how to improve the situation myself. We have a similar problem with ‘guix pull’ in fact: should we first compile everything and then run, or compile everything but the (gnu packages …) modules, or…? Ludo’.
