NetworkManager is installed by default, and NM sends configuration to wpa_supplicant using a different control interface, not the config file. If you want to take the wifi interface out from NM's control, I think you can add the interface to /etc/network/interfaces and NM will then ignore it, and you can run wpa_supplicant manually with the '-i wlan0' option to point it to the right interface, and when you've got a config file, use '-c /path/to/config/file' to give it your configuration. Or, since I'm a NetworkManager developer, is there something that you're not sure how to make NM do, or are you just looking to experiment?
