Cuirass job names and package variants

[Ludovic Courtès]

Hello!

Cuirass support in (gnu ci) computes job names as a function of package
names (the ‘job-name’ procedure).  I wanted to build several package
variants using ‘--with-input’, which I expressed in a manifest:

  https://gitlab.inria.fr/guix-hpc/guix-hpc/-/blob/master/manifest#L33-50

However, variants of a given package have the same package name/version,
and thus the same job name.  Apparently Cuirass only takes the first job
with a given name into account and dismisses subsequent ones.

What would be a good way to address this, either in Cuirass or in the
user config?

I thought about changing the name that appears in manifest entries
(without changing the actual package name), but (@ (gnu ci)
manifests->packages) ignores manifest entry names.

Ideas?

Thanks,
Ludo’.
