J'ai écrit un petit script bash une fois qui prend un ISO Arch Linux et génère un nouveau ISO avec une image racine modifiée qui fait une installation entièrement automatisée. Cela inclut le partitionnement ainsi que l'installation et la configuration du système avec Xorg, FVWM et Chromium. Le système installé se connectera automatiquement et démarrera Chromium. Mettez simplement la nouvelle ISO sur une clé USB et détendez-vous. ;-)
Avertissement: le script est fourni tel quel, aucune garantie n'est donnée. Je ne l'ai pas utilisé depuis un moment, il pourrait donc avoir besoin d'un ajustement ici ou là. Modifiez au besoin.
