Using Cuirass to build substitutions for pkgs in manifest

[Jiří Špaček]

Hello,

I'm trying to setup cuirass configured as GuixSD  service but I'm getting stuck.

Basically, I'm trying to use cuirass for building substitutions for
packages from my manifest (ie. only those that I actively use on my
systems). My manifest contains package provided by standard Guix
distribution alongside with a few custom packages coming from my own
channel.

My Curiass config (modified version of example mentioned in the Guix
Reference Manual) can be seen below:

(define %cuirass-specs
  #~(list
     '((#:name . "my-manifest")
       (#:load-path-inputs . ("guix"))
       (#:package-path-inputs . ("personal"))
       (#:proc-input . "guix")
       (#:proc-file . "build-aux/cuirass/gnu-system.scm")
       (#:proc . cuirass-jobs)
       (#:proc-args . ((subset . "manifests")
                       (systems . ("x86_64-linux"))
                       (manifests . (("config" . "guix/manifest.scm")))))
       (#:inputs . (((#:name . "guix")
                     (#:url . "git://git.savannah.gnu.org/guix.git")
                     (#:load-path . ".")
                     (#:branch . "master")
                     (#:no-compile? . #t))
                    ((#:name . "config")
                     (#:url .
"https://github.com/geostarling/guix-manifest.git";)
                     (#:load-path . ".")
                     (#:branch . "master")
                     (#:no-compile? . #t))
                    ((#:name . "personal")
                     (#:url .
"https://github.com/geostarling/guix-packages.git";)
                     (#:load-path . ".")
                     (#:branch . "master")
                     (#:no-compile? . #t)))))))



When I try to start Cuirass service with `herd start cuirass` I get
following error in cuirass log:

The service itself won't crash, no packages will get built though.

I suspect the problem lies in `proc-args` definition or in improper
`(#:proc . cuirass-jobs)` use, but I was unable to find any more info
on these parameters.

Also, I would be very grateful if someone could share their Cuirass
config that does something similar.

Thank you.
