+fixes:
+  - os-net-config always logs the message "Using mapping file at:
+    /etc/os-net-config/mapping.yaml" even if the file does not exist, in which
+    case it's not actually being used at all. Move the log message to only be
+    shown if the mapping file actually exists and is used. In the case where no
+    mapping file is used, also log a message indicating such.
