Configurare Buildbot per le Macchine Virtuali - Ubuntu 10.04 (alpha), i386 e amd64

Abilitare sudo senza password:

sudo VISUAL=vi visudo
# decommentare `%sudo ALL=NOPASSWD: ALL' line in `visudo`, and move to end.

Modificare /boot/grub/menu.lst:

sudo vi /etc/default/grub

# Aggiungere/modificare queste voci:
    GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"
    GRUB_TERMINAL="serial"
    GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1"

sudo update-grub

Vedi sopra per creare my.seed e sources.append.

cat >sources.append <<END
