                     even if the device name changes due to differences in
                     hardware configuration.

+                    By default, <filename>ROOT_VM</filename> is set
                     as follows:

                     However, you can change this to locate the root device
                     using the disk signature instead:
                     <literallayout class='monospaced'>
