标题: 关于修改System Properity的问题
我现在系统定义为，当RJ45 插入，则置位rj45.ethernet.state,置位这个将被init.rc里面的
on property:rj45.ethernet.state=attached
start dhcpcd_eth0
将启动dhcpcd程序，
拔出类似定义

但是，我们在程序里面设置这个properity，却没有权限。导致设置失败。
我们需要如下方式修改：
/media/doraemon/works/android/mtk/6572/QPlayer/eng/alps/system/core/init/property_service.c
