之前因为比较忙,导致树莓派一直在吃灰,同时,貌似官方推荐的Raspbian有点儿问题,配置文件一直保存不了,然后看着别人玩儿Arch好像很不错的样子就试玩了一把,其中装系统没啥说的,关键是分区,Arch Linux提供给树莓派的是img镜像,导致镜像多大,总共可用的空间就多大,这明显是不能接受的,所以搜索了一下,把分区搞定了,最近确实变懒了,直接上转载来的文章

Welcome to fdisk (util-linux 2.23.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
