CTRL-EVENT-REGDOM-CHANGE on latest Raspbian Jessie Lite

I’d get following errors when I ran wpa_supplicant to connect to my home network from Raspbian Jessie Lite (using CLI, of course)

wlan0: SME: Trying to authenticate with 0c:xx:xx:xx:xx:xx (SSID=’MYSSID’ freq=2412 MHz)
wlan0: Trying to associate with 0c:xx:xx:xx:xx:xx (SSID=’MYSSID’ freq =2412 MHz)
wlan0: Associated with 0c:xx:xx:xx:xx:xx
wlan0: CTRL-EVENT-DISCONNECTED bssid=0c:xx:xx:xx:xx:xx reason=3 locally_generate d=1
wlan0: CTRL-EVENT-REGDOM-CHANGE init=CORE type=WORLD

It turns out that wpa_supplicant runs as a service and is to be controlled through wpa_cli. You can go that way, or you can simply killall wpa_supplicant if you’re in a hurry and run  the usual command line, and the errors will go away.
