Ce script construit Xen, un noyau Linux 64 bits de l'arborescence Raspberry Pi, et intègre un rootfs Ubuntu 20.04 64 bits minimal pour le Raspberry Pi 4. Une version récente d'Ubuntu est requise pour exécuter le script de construction. Une connexion Internet est requise. 8 Go de RAM ou plus sont recommandés et 10 Go d'espace disque libre.
Usage:
./rpixen.sh
Lorsque le script est terminé, flasher l'image sur la carte SD avec (par exemple) :
umount /dev/sdX1 umount /dev/sdX2 sudo dd if=rpixen.img of=/dev/sdX bs=8M sync
Pour se connecter utiliser le nom d'utilisateur Dornerworks et le mot de passe Dornerworks.
Pour installer un bureau graphique, exécuter la commande sudo apt install ubuntu-desktop et redémarrer.
