+
+The `-kubeconfig-path` flag specifies the absolute path to the kubelet configuration
+file on the node. This configuration is primarily used by NFD to determine the
+swap behavior set on the node. Kubernetes currently supports two types of swap
+behavior `NoSwap` and `LimitedSwap`. It is important to note that even if swap is
+enabled at the system level, a setting of `NoSwap` in the kubelet configuration
+means that Kubernetes workloads will not be permitted to use swap space—although
+non-Kubernetes processes on the node may still do so.
