# Trap CTRL-ALT-DELETE

ca::ctrlaltdel:/sbin/shutdown -t3 -r now

# When our UPS tells us power has failed, assume we have a few minutes # of power left.

Schedule a shutdown for 2 minutes from now.

# This does, of course, assume you have powerd installed and your # UPS connected and working correctly.

pf::powerfail:/sbin/shutdown -f -h +2 \

# If power was restored before the shutdown kicked in, cancel it.

pr:12345:powerokwait:/sbin/shutdown -c \

# Run gettys in standard runlevels 1:2345:respawn:/sbin/mingetty tty1

2:2345:respawn:/sbin/mingetty tty2 3:2345:respawn:/sbin/mingetty tty3 4:2345:respawn:/sbin/mingetty tty4 5:2345:respawn:/sbin/mingetty tty5 6:2345:respawn:/sbin/mingetty tty6

# Run xdm in runlevel 5

x:5:respawn:/etc/X11/prefdm -nodaemon 然后把文件删除，重启系统： [root@51cto ~]# rm /etc/inittab

rm：是否删除 一般文件 “/etc/inittab”? y [root@51cto ~]# reboot

结果显示不存在系统运行的进程，就是因为/etc/inittab的丢失造成的，当然修复的话不可能

手写进去了，那么多内容啊！

这时候进入救援模式，安装initscripts软件包，自动创建/etc/inittab文件 当然要通过mount /dev/dhc

/media/cdrom/挂载光驱，然后安装rpm包

登陆了系统，可以查看到该文件了！
