 It is recommended that you move the existing `service` entry with
 `class charger` to the `init.rc` file in your custom health service.
 
+If there are existing actions in the rc file triggered by
+`on property:init.svc.<name>=running`, where `<name>` is the name of your
+existing charger service (usually `vendor.charger`), then the name of the
+service must be kept as-is. If you modify the name of the service, the actions
+are not triggered properly.

 Modify the entry to invoke the health service binary with `--charger` argument.
