Hello,

Here's a patch adding support for build products downloading in
Cuirass. It is inspired by a similar mechanism in Hydra.

Attached a screenshot of what I obtained with the following
specification:

--8<---------------cut here---------------start------------->8---
(define hello-master
  '((#:name . "guix-master")
    (#:load-path-inputs . ())
    (#:package-path-inputs . ())
    (#:proc-input . "guix")
    (#:proc-file . "build-aux/cuirass/gnu-system.scm")
    (#:proc . cuirass-jobs)
    (#:proc-args (subset . "all"))
    (#:inputs . (((#:name . "guix")
                  (#:url . "https://gitlab.com/mothacehe/guix")
                  (#:load-path . ".")
                  (#:branch . "master")
                  (#:no-compile? . #t))))
    (#:build-outputs . (((#:job . "iso9660-image*")
                         (#:type . "iso")
                         (#:output . "out")
                         (#:path . ""))))))

(list hello-master)
--8<---------------cut here---------------end--------------->8---

Thanks,

Mathieu
