Also, the message is missing the point. It's not that it's deprecated and sometimes causes problems -- it's that udev *changed behavior* and breaks your system if you have CONFIG_FW_LOADER_USER_HELPER=y. If udev logged something (for a couple of years), that would be a different story. --Andy -- To unsubscribe from this list: send the line "unsubscribe linux-hotplug" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
