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
