Hi Guix people :)

I'm starting guix, picking information when needed into documentation.

I'm facing difficulties with channels.scm since i start using "guix home", i read the doc page, but i need some other things to understand.

Here my logic to start just after install :

1 - I modify my //etc/guix/channels.scm/ file to add some modules : /nonguix/ (my computer don't work well without) and /emacs-native-dep/ from flatwhatson flat channel.

2 - I /guix -E guix system reconfigure /etc/config.scm/, /guix pull/, and everything goes well

3 - Like explained in the doc, I run /guix home import ~/src/guix-config /that generate /a //home-configuration.scm//

/4 - /Into /home-configuration.scm///i add the package htop and /emacs-native-comp/

5 - In the guix home doc the next command is /guix home reconfigure config.scm /but this is probably a typo and i run /guix home reconfigure ~/src/guix-config/home-configuration.scm/

6 - Everything goes well, emacs-native-dep compile during 1 hour, problems arrive after that.

7 - I'm moving the //etc/guix/config.scm/ and //etc/guix/channels.scm /to my home /~/.config/guix/ , /and i run /sudo guix system reconfigure ~/.config/guix/system.scm///*, that fail*/, /it seems the module (nongnu and emacs-native-dep) are not referenced, like the error say /"no code for module ( nongnu ..." /But when i run /guix system describe/, the corresponding channel are well defined. /

After that, i try many thing, like moving channels.scm and system.scm back to /etc/guix/ but every reconfigure command fail in link with channel/module not recognized (emacs-native-dep or nongnu)

- /guix home reconfigure ~/src/guix-config/home-configuration.scm/

- /guix system reconfigure ~/.config/guix/system.scm/

- /guix system reconfigure ~/etc/guix/config.scm/

So my question is first, why that fail after switching to guix home ? and how and where i need to define/set correctly the /channel.scm/ file to repair that ?

For example, /guix system//describe/ and /guix home describe/ and /guix describe/ return all different channel referenced, how i manage that ?

I suppose there is a "workflow to use well guix home"? but this is not actually in the doc. For example, perhaps after creating and switching to guix home profile, running guix system is impossible or prohibited ? I suppose this will be added in the future.

Thanks a lot for your help.
