阅读以下说明，回答问题。 [说明] Linux系统开机引导时首先启动内核，由内核检查和初始化硬件设备，载入设备的驱动程序模块，安装root文件系统，然后内核将启动一个名为init的进程。在init运行完成并启动其他必要的后续进程后，系统开始运行，引导过程结束。init进程启动时需要读取inittab配置文件，该文件确定init在系统启动和关机时的工作特性。典型的inittab文件内容见以下清单： # #inittab This file describes how the INIT pT ocess should set up #the system In a certain run-level． # #Default runleve1.The runlevels used by RHS are： #0-halt(Do NOT set initdefault to this) # 1-Single user mode # 2-Multiuser，without NFS(The same as 3，if you do not have networking) # 3-Full multiuser mode # 4-unused # 5-X11 # 6-reboot(Do NOT set initdefault to this) # id:5:initdefault: #System initialization． s1::sysinit:/etC/rc.d/rc.sysinit 10:0:wait:/etc/rc.d/rc 0 11:1:wait:/etc/to.d/rc 1 12:2:wait:/etc/rc.d/rc 2 13:3:wait:/etc/rc.d/rc 3 14:4:wait:/etc/rc.d/rc 4 15:5:wait:/etc/rc.d/rc 5 16:6:wait:/etc/rc.d/rc 6 #Trap CTRL-ALT-DELETE Ca::ctrlaltdel:/sbir/shutdown-t3-r now #When our UPS tells us power has falled,assume we have a few minutes #of power left.
