+
+**`devices`** (array of objects, OPTIONAL) lists devices that MUST be available in the container.
+The runtime MAY supply them however it likes.
+
+Each entry has the following structure:
+
+* **`type`** *(string, REQUIRED)* - type of device: `c`, `b`, `u` or `p`.
+* **`path`** *(string, REQUIRED)* - full path to device inside container.
+    If a file already exists at `path` that does not match the requested device, the runtime MUST generate an error.
+* **`major, minor`** *(int64, REQUIRED unless `type` is `p`)* - major, minor numbers for the device.
+* **`fileMode`** *(uint32, OPTIONAL)* - file mode for the device.
+
+The same `type`, `major` and `minor` SHOULD NOT be used for multiple devices.
