>Description:
        
When specifying a different ctrl_interface in /etc/wpa_supplicant.conf, 
wpa_supplicant
itself will happily adhere to your wishes and create the directory where you 
pointed it
to, adding socket(s) for each card and so on.

wpa_cli will fail to find the socket though.

Part of ktrace output from wpa_cli:
 2267      1 wpa_cli  CALL  open(0x804f33c,4,0)
 2267      1 wpa_cli  NAMI  "/var/run/wpa_supplicant"
 2267      1 wpa_cli  RET   open -1 errno 2 No such file or directory
                  
You can see how it looks at the wrong place (the standard location).
I have specified ctrl_interface=/var/run/wpa_fun in my wpa_supplicant.conf

But the manpage (wpa_supplicant.conf(5)) mentions..:

     ctrl_interface
             The pathname of the directory in which wpa_supplicant(8) creates
             UNIX domain socket files for communication with frontend programs
             such as wpa_cli(8).


>How-To-Repeat:
        add ctrl_interface=/var/run/wpa_whatever to your wpa_supplicant.conf
        Start wpa_supplicant (I use the rc.d script)
        Try and start wpa_cli. It'll complain and fail.

        Dunno.
