aitor, please notice that the pid file for wpa_supplicant can be
literally *anywhere*. At the moment, in Devuan Beowulf, it is stored
in the folder /var/run/wpa_supplicant/. But this is just very
unreliable, IMHO. Please also consider that `wpa_supplicant(8)` has an
option "-P" that allows to specify the path to pidfile...
