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

["Sébastien Rey-Coyrehourcq" <sebastien.rey-coyrehourcq@univ-rouen.fr>]

Hi,

My other question remain about guix home / guix system relation, and 
sudo, but jpoiret found my main problem, my channels.scm are not well 
defined / not good ...

- I made (cons * (channel ...)) (cons* (channel ...)) etc.

- and .. the correct way is (cons * (channel ...) (channel ...))

Everything run fine now with *guix system reconfigure 
/.config/guix/system.scm*

Best
