612 	 * For UNIX domain sockets (default on Linux and BSD): This is a
613 	 * directory that will be created for UNIX domain sockets for listening
614 	 * to requests from external programs (CLI/GUI, etc.) for status
615 	 * information and configuration. The socket file will be named based

625 	 * %wpa_supplicant as root (since it needs to change network

629 	 * configuration, this access needs to be protected in many

631 	 * 0 (root). If you want to allow non-root users to use the

633 	 * match with that group. Add users that should have control
