[root@lyn rc.d]# more /etc/inittab

#

# inittab       This file describes how the INIT process should set up

#               the system in a certain run-level.

#

# Author:       Miquel van Smoorenburg,

#               Modified for RHS Linux by Marc Ewing and Donnie Barnes

#

 

# Default runlevel. The runlevels used by RHS are:

0 - halt (Do NOT set initdefault to this) 系统停机状态 rc0.d

1 - SIngle user mode 单用户工作状态 rc1.d

2 - Multiuser, without NFS (The same as 3,if you do not have networking ) 多用户状态（没有NFS【文件服务系统】）  rc2.d

3 - Full multiuser mode 多用户状态（有NFS） rc3.d

4 - unused 系统未使用，留给用户 rc4.d

5 - X11 图形界面 rc5.d

6 - reboot (Do NOT set initdefault to this) 系统正常关闭并重新启动 rc6.d
