+    Custom partitioning YAML file can now be specified using partitioning_file
+    variable which contains a path to the YAML file describing the partitions
+    layout. For example:
+
+    .. code-block:: yaml
+
+        - local_loop:
+            name: image0
+        - partitioning:
+            base: image0
+            label: mbr
+            partitions:
+              - name: root
+                flags: [ boot,primary ]
+                size: 6G
+                mkfs:
+                  type: xfs
