+[WARNING]
+====
+Modifying the file `/etc/sysconfig/kubelet` directly is not supported.
+
+The changes made to this file will not persist through an update/upgrade of the software.
+Please follow the instructions below to change the configuration for `kubelet` persistently.
+====
+
+[NOTE]
+====
+This procedure does not override the default configuration but amends the changes
+from the "drop-in" configuration.
+
+Please refer to: https://www.freedesktop.org/software/systemd/man/systemd.unit.html
+====
+
+If you wish to modify the configuration for `kubelet` you must use the "drop-in"
+configuration feature of systemd. The steps need to be performed on each cluster
+node whose `kubelet` you wish to reconfigure.
+
+. Create an appropriate `.conf` file (e.g. `resource-handling.conf`) in `/usr/lib/systemd/system/kubelet.service.d/` with your desired changes.
+.
+. Reload the service definitions

+sudo systemctl daemon-reload
