Disable CTRL-ALT-DEL in Ubuntu 10.10 ( Maverick Meerkat )

I have commented “exec shutdown … ” in /etc/init/control-alt-delete.conf.

# control-alt-delete - emergency keypress handling
#
# This task is run whenever the Control-Alt-Delete key combination is
# pressed, and performs a safe reboot of the machine.
