We have already exposed device ID in the output of device ID in J fields. Also sd_device_get_device_id() and sd_device_new_from_device_id() are already public. Hence, making udevadm accept device IDs may be useful. With this change, as we save several data in /run/udev with device ID, we can call udevadm something like the following: ``` udevadm info $(ls /run/udev/tags/uaccess) ``` Then, we can show all devices that has uaccess tag.
