28 Ueventd listens to the kernel uevent sockets and creates/deletes nodes in `/dev` based on the
34 to this node at `/dev/block/<type>/<parent device>/<basename uevent DEVPATH>`,
35 `/dev/block/<type>/<parent device>/by-name/<uevent PARTNAME>`, and `/dev/block/by-name/<uevent
37 2. USB devices are created as `/dev/<uevent DEVNAME>` if `DEVNAME` was specified for the uevent,
39 `device_id` is `uevent MINOR % 128 + 1`.
40 3. All other devices are created as `/dev/<basename uevent DEVPATH>`
60 `subsystem_name` is used to match uevent `SUBSYSTEM` value
63 1. `uevent_devname` specifies that the name of the node will be the uevent `DEVNAME`
64 2. `uevent_devpath` specified that the name of the node will be basename uevent `DEVPATH`
