Re: Guix home, guix system, channels, some noob questions

[Sébastien Rey-Coyrehourcq]

Hi,

Thanks Julien,

I see on the doc that *sudo* run command as user and not as root like 
other distro. So, to be sure, if i run *sudo guix something*, i don't 
change user to run this command isn't it ?

Actually i only work with my account "myuser" into group 
("users","wheel",etc.) using or not using *sudo* (this is not clear when 
i need or not) for running *guix* command.

About the commands with /.config/guix/channels.scm (see content here 
https://paste.debian.net/1240553)  :

a) *guix describe* and *sudo guix describe* and *sudo -E guix describe* 
return

With jpoiret, i try to resolve the issue on chat, i also try to run 
manually *guix pull -C ./config/guix/channels.scm* without success.

A *command -v guix* return */home/myuser/.config/current/bin/guix*

Best regards,

SR
