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.

根据上述inittab文件的内容,系统在引导过程结束前,至少还要执行______进程。

A.rc.sysinit

B.rc.sysinit和rc 5

C.rc.sysinit、rc 0、rc 1、rc 2、rc 3、rc 4、rc 5和rc 6

D.rc 0、rc 1、rc 2、rc 3、rc 4、rc 5和rc 6
