If client certificates, keys or other files are needed, these should be stored under `/etc/wpa_supplicant` and owned by `wpa_supplicant` to ensure the daemon can read them.
Similarly, the `ctrl_interface` directory set in `wpa_supplicant`'s conf must be writeable by the `wpa_supplicant` user so that the `wpa_supplicant` daemon can start successfully. If you were changing `ctrl_interface` in [extraConfig](#opt-networking.wireless.extraConfig) or in `/etc/wpa_supplicant/imperative.conf`, please remove that line.
Also, the {option}`networking.wireless.userControlled.group` option has been removed since there is now a dedicated `wpa_supplicant` group to control the daemon, and {option}`networking.wireless.userControlled.enable` has been renamed to [](#opt-networking.wireless.userControlled).
No functionality should have been impacted by these changes (including controlling via `wpa_cli`, integration with NetworkManager or connman), but if you find any problems, please open an issue on GitHub.
