Installer ubuntu dans une partition expérimentale ZFS chiffrée
Bonjour
Enfin le nouveau DAILY permet de détecter le disque USB à condition de prendre certaines précautions.
J'ai donc pu installer un ubuntu standard sur la totalité du disque.
=> Fabrication d'une partition FAT32 de 1073 Mo.
Je tente maintenant une installation expérimentale chiffrée.
Voici une partie de la trace
