Ouveture LUCKS via SSH

$ sudo apt-get install dropbear busybox-static
$ sudo nano /etc/initramfs-tools/initramfs.conf

IP=192.168.0.191::192.168.0.254:255.255.255.0::eth1:off # IP différente pour éviter problèmes de fingerprint

/!\ Interface eth0 initialisée au boot ; plus possible d'utiliser udev pour renommer les interfaces.
