Need Help Setting Up WIFI From Chroot On Headless Server

[DevNull]

I have a raspberry pi with raspbian on it right now and I want to put arch linux arm on it. It has a powered hub hooked up to it with a wifi dongle and a usb sd card reader with a sd card with arch linux arm on it. I have been able to chroot into arch linux arm and use pacman and other stuff. I want to setup wifi on arch linux arm from the chroot so that I can unplug my raspbian sd card and plug in my arch linux arm and it will boot up connect to wifi and I can ssh into it. My wifi dongle worked out the box with no additional downloads so I assume its supported by the linux kernel by default(maybe not...). I have read https://wiki.archlinux.org/index.php/Wireless_Setup and all the stuff about netcfg and wicd and network manager. So far I think I can do it using this info https://wiki.archlinux.org/index.php/Wi ... ng_systemd but I want it to auto reconnect on disconnect or after I unplug and replug in the dongle and I want it to be able to connect to multiple networks with priority. For auto reconnect I think netcfg is the best option for setting up from a chroot but i cant figure out how to set that up. So will the manual method with systemd work with auto reconnect or how can you setup netcfg,wicd,... from chroot?

BTW I could hook up a monitor and keyboard to the pi and set it up using wicd with no problems but thats too easy and I want to learn something.
