# BRLTTY is now able to switch to running as an unprivileged user, using    #
# only a few capabilities), and we don't want to be using CAP_DAC_OVERRIDE. #
# It uses uinput in order to support some important features, including:    #
# *  Keyboard Key Tables                                                    #
# *  Injecting arbitrary key combinations typed on braille devices.         #
