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…?
