Udevadm info starts with the device specified by the devpath and then |
| 4 |
walks up the chain of parent devices. It prints for every device |
| 5 |
found, all possible attributes in the udev rules key format. |
| 6 |
A rule to match, can be composed by the attributes of the device |
| 7 |
and the attributes from one single parent device. |
