Ceci est une ancienne révision du document !
Il s'agit de récupérer un script shell d'installation, de le rendre exécutable et de le lancer. Celà installera Guix aux côtés des autres gestionnaires de paquetage sans les altérer de quelque façon que ce soit.

J'ai copié-collé le script dans un nouveau fichier à l'aide de vim :

Ensuite j'ai rendu le fichier exécutable :
# chmod +x guix-install.sh
