wpa_supplicant has no non-daemon mode. When it exits, it deconfigures the interface. AFAIU, netman uses ifupdown but bypasses /etc/network/interfaces, writing its own alternate interfaces files (utilized by spawning 'ifup -i ...'). These files use the "fire-and-forget" mode of the wpa_supplicant ifconfig plugin (wpa_essid and so forth). Actually, I'm not sure exactly how much forgetting ifupdown does. But I know that this mode is *not* utilising the ability of wpa_supplicant to handle multiple networks; netman seemed to repeatedly call a helper in order to do what wpa_supplicant could do, if properly configured. The developer intends to call wpa_* directly at some point; I hope that he takes the opportunity to make it use wpa_supplicant's abilities. > > I don't know where wicd is in this plot. It's a two-part python/dbus interface that runs wpa_supplicant from a daemon and controls it from a client.
