How to have guile module available during sudo system reconfigure?

How to have guile module available during sudo system reconfigure?

Hello Guix,

I did run into an interesting (frustrating?) problem.  I created a
package that bundles few Guile modules of my making.  I installed it
into my home environment and wanted to use helpers from it in my system
configuration.  However I am not sure how to do that.

When I do

--8<---------------cut here---------------start------------->8---
guix system build some/config.scm
--8<---------------cut here---------------end--------------->8---

The system builds and everything is fine.

However when try to reconfigure the system using

--8<---------------cut here---------------start------------->8---
sudo guix system reconfigure some/config.scm
--8<---------------cut here---------------end--------------->8---

It fails with a very descriptive error of

--8<---------------cut here---------------start------------->8---
ice-9/eval.scm:142:16: In procedure compile-top-call:
error: system-add-luks: unbound variable
hint: Did you forget `(use-modules (wolfsnet systems))'?
--8<---------------cut here---------------end--------------->8---

I managed to track it down to module from my package not being
importable.  Since I have it in my home environment, all non-sudo
commands work, however when I add in the sudo to actually install the
new system it does not find it.

I am not sure what to do about this.  I have tried to install the
package into system, but that does not seem to have any effect.

-E flag to sudo was suggested on IRC, and that works, however
documentation does not use it so I am bit scared of various site
effects it could have.

Does anyone know how to approach this?

Tomas

I have settled on a different reconfiguration method on my systems to
ensure usage of modules brought in by guix pull

sudo guix system reconfigure -e '(@ (systems akashi) operating-system*)

I hope this is enough to work around your issue.

I've never done that, but have you tried setting GUILE_LOAD_PATH?

$ sudo GUILE_LOAD_PATH="myguile/modules:$GUILE_LOAD_PATH" guix system reconfigure some/config.scm

Cheers,

If you have a personal Guix channel, any Guile code in it gets 
added to your load path.  I use this to include helpers which ease 
both system and home configurations, ex. this code for helping 
with offloading builds[1], or home services to launch 
jellyfin-mpv-shim[2] when I log in.

Perhaps the same setup would work for you, too.

Thanks,
