echo "Setting Network......" 修改这里, 加入我写的setnetwork脚本,
. /etc/setnetwork 这样网络设置在每台机上都可以重新设置而不是更改文件.
3、上一步最后有一个setnetwork脚本，这一步写出。我的脚本编写不会， 只好从其它地方抄过来，有一些错误，需要请高手改写。这个文件有点大， 贴在最后吧！
4、将一些网络配置的文件删除如：hosts, mygate等。上一步的network在启动时会生成这些配置文件。
五、 备份几个目录，在4.3 rc脚本中的MFS部分那个文件。
在/usr/live/ LiveCD根目录下建立文件夹：mfs 然后：
# tar cvzfp mfs/mfs.tgz dev etc home var
