Subject: bug#44399: Cuirass problem with building from manifest file

From: david larsson <[email-masked]>

Hi!

I am unable to build a simple manifest containing the hello package, see 
below. I tried imitating the manual 
https://guix.gnu.org/manual/en/html_node/Continuous-Integration.html but 
perhaps the manifest.scm is not supposed to contain a regular manifest 
or maybe that config example is outdated?

============================
The hello.scm file - works fine using guix package -m hello.scm
============================

cat /home/cuirass/my-guixsd-config.sh/manifests/hello.scm
(specifications->manifest
  (append (list "hello")
          '()))

 From /var/log/cuirass.log
