Created attachment 277195 [details] One-interface unit for wpa_supplicant (wpa_supplicant@.service) As I mentioned earlier, that service file is useful only to NetworkManager, and I'm not even sure if NM is not a better place to install it. I'm attaching a simple unit of mine which allows running wpa_supplicant on a single interface (without NM).
CC-ing NetworkManager maintainers too to see what they think on #c1.
(In reply to comment #1) > Created attachment 277195 [details] > One-interface unit for wpa_supplicant (wpa_supplicant@.service) I would suggest changing Description=WPA supplicant daemon (interface-specific version) to something like Description=WPA supplicant daemon on %I
Ok. Added -r3 to tree with systemd unit
