阅读以下说明,回答问题1至问题8。[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 process should set upthe system in a certain nm-level.Default nmlevel. The nmlevels used by RHS are:0 - halt (Do NOT set initdefault to this )1 - Single user mode2-Multiuser, without NFS (The same as 3, if you do not have networking)3 - Full multiuser mode4 - unused5-Xll6 - reboot (Do NOT set initdefault to this )id:5:initdefault:System initialization.si::sysinit:/etc/rc.d/rc.sysinit10:0:wait:/etc/rc.d/rc 011:1:wait:/ete/rc.d/rc 112:2:wait:/etc/rc.d/rc 213:3:wait:/etc/rc,d/rc 314:4:wait:/etc/rc.d/rc 415:5:wait:/etc/rc.d/rc 516:6:wait:/etc/rc.d/rc 6Trap CTRL-ALT-DELETEea::ctrlaltdel:/sbin/shutdown -t3 -r nowWhen our UPS tells us power has failed, assume we have a few minutesof power left.
