上篇文章介绍了Arch操作系统的网络配置，包括动态DHCP以及静态IP获取的配置方法：http://note.t4x.org/basic/arch-linux-network/，此次介绍一下开机启动的问题。
顺便说一下Centos 7 中rc.local其实依然是可以使用的，无法使用的原因是由于/etc/rc.d/rc.local中没有X权限，增加一个执行权限即可。
既然centos中的可以使用，哪么arch linux中其实也是可以使用的。直接copycentos中的资料即可。

rc.loca在Arch中无法启动的原因是由于我在rc.loca中没有设置#!/bin/sh导致的！！！文 章 源 自 note.t4x.orgByrd's Blog-https://note.t4x.org/basic/arch-linux-rc-local/
