You can check for the location of the ctrl_interface domain socket (that may
be in a different location according to config file used) or pidfile (which
is what the wpa-ifupdown init script/hack uses to identify interfaces bound
by wpa_supplicant/wpa_cli, and it is a fixed location).
Is this a workaround for #383168? If so, my current kludge is to have the
suspend manager, in my case it was hibernate but now it is powersave, stop
the wpa-ifupdown service on suspend.
Thanks, Kel.
