Switch from NM to netctl

I did that in the good old days, and I switched to NM because I didn't know then the wifi-menu interface. But, for a sneaky bug I don't understand, all my wireless interfaces became "Unavailable" on all my computers. No matter if I uninstall, reset anything related to NM. So, back to netctl with a nice script to automate connections
