取消多余的tty和静止Ctrl+Alt+Del

1、禁止系统的Ctrl+Alt+Del

# cat /etc/event.d/control-alt-delete 

# # control-alt-delete - emergency keypress handling

# #

# # This task is run whenever the Control-Alt-Delete key combination is

# # pressed.  Usually used to shut down the machine.

# 

# start on control-alt-delete

# 

# exec /sbin/shutdown -r now "Control-Alt-Delete pressed"

2、禁止Fluxbox的Ctrl+Alt+Del

# cat ~/.fluxbox/keys | grep -i exit

# exit fluxbox

# Control Mod1 Delete :Exit

3、去掉系统多余的tty

# cat /etc/event.d/tty6 

# # tty6 - getty

# #

# # This service maintains a getty on tty6 from the point the system is

# # started until it is shut down again.

# 

# start on stopped rc2

# start on stopped rc3

# start on stopped rc4

# start on started prefdm

# 

# stop on runlevel 0

# stop on runlevel 1

# stop on runlevel 6

# 

# respawn

# exec /sbin/mingetty tty6

# ps -ef | grep -i tty
