Hello o/
Further investigations to insert
the hurd-vm in /etc/config.scm
In my attempt at config.scm, inspired both by my own file
and from examples found on the Internet, I've
tried to use (define %my-gnome as well and
(modify-services %desktop-services, knowing that I'm missing
at least 1 module related to the package list. I've
tried several, but I can't figure out which one (or
which...)
$ sudo guix system reconfigure /etc/config.scm
--8<---------------cut here---------------start------------->8---
ce-9/eval.scm:223:20: In procedure proc:
erreur : packages : variable non liée
conseil : Auriez-vous oublié un `use-modules' ?
--8<---------------cut here---------------end--------------->8---
As I only use Guix System, I'm aware that I'd better build myself a
a virtual machine to test this kind of configuration.
Secondly, I'm also aware that even if my
(use-modules) field was satisfied, there might still be other
problems...
Here's the failing test, what do you think?
/etc/config.scm

Thank you in advance if you can point me to a way :)
