看看/etc/rcS.d/README这个文件里边提供init S的相关简单解释:
The scripts in this directory whose names begin with an 'S' are executed
once when booting the system, even when booting directly into single user(single user不就是init 1??)
mode.
The scripts are all symbolic links whose targets are located in
/etc/init.d/ .
To disable a script in this directory, rename it so that it begins with
a 'K'.
