{{tag>Brouillon Paquet Déploiement}}

= Guix le gestionnaire de paquets complémentaire multi distro

Avantage :
* Indépendance par rapport à la distro
* Reproductibilité, c'est une sorte de virtualenv pour des binaires
* Réversibilité
* Permettre à des utilisateurs (non root) de facilement installer programmes  
* Compilation
** Plus de souplesse 
** Plus de confiance dans un code source vérifiable que dans un fichier binaire

Inconvénient :
* Toujours en bêta
* Compilation
** Plus lent
** Nécessite un compilateur installé et plusieurs bibliothèques (libraries)  
* Que GNU/Linux, ne support pas BSD et autres
