在树莓派上使用自编译的LEDE固件，安装SSR或KoolProxy后，luci界面出现错误。对比官方固件，发现问题出在sys.lua文件差异。修复sys.lua文件后，问题解决。

一直有个问题，我自己编译的所有的LEDE的固件，在我使用opkg安装完ssr或者kp之后，打开luci界面会出现：

attemp to call a nil field net.arptable (a nil value)

诸如这个消息。

当我使用潘多拉的固件或者是官方的固件的时候，发现是正常的，这个问题就不会出现，这是为啥来？

原因就在自己编译的LEDE固件的sys.lua文件和官方的这个文件不一样！！！

把自己的文件改一下：
