Proposta di modifica dell' imagine fuss-server cloudinit
by Von Guggenberg, Michael
Salve,
Progongo la migrazione del disco formatato con singola partizione in
ext4 agganciata alla vm fuss-server 10 cloudinit ad uno formatato con
LVM e vari punti di mount per /boot /root /var,la home dell' utente
clonezilla e una partizione dedicata per swap. Vorrei anche aggiungere
contrib e non-free a sources.list
sda è il disco nuov a 140G
sdb2 la partizione / ext4
