linuxonandroid ubuntu12.04-v4-core启动文件(N7100 Android 4.3)
一. 测试环境
手机型号:三星 N7100 Android 4.3 已root，已禁用selinux(Permissive)
系统版本:linuxonandroid ubuntu12.04-v4-core
small和full应该也可以使用此脚本。安装教程:

环境的搭建不再详述。
二. 修改后的bootscript4-3.sh
官网的脚本bootscript.sh，经本人测试，在N7100 Android4.3上有点小问题。
在官网的脚本基础上，修改网卡的接口为wlan0,修改了存储卡的名字为手机上显示的实际名字。测试可以正常使用。
全部代码如下:
