Installation d'une Debian sur une carte flash.
Préparation de la carte
Suppression des partitions
On commence par supprimer les partitions déjà crées sur la carte.
debian:/home/sbolay# fdisk /dev/sdb

Calling ioctl() to re-read partition table. Syncing disks.
Une fois les partitions supprimées, on réinitialise la carte à zéro.
debian:/home/sbolay# dd if=/dev/zero of=/dev/sdb

Création des partitions
Une fois la carte entièrement réinitialisée, on crée la partition qui accueillera le système.
debian:/home/sbolay# fdisk /dev/sdb

Formatage de la partition
On crée la partition qui contiendra notre Debian.
