112 # invocations. You can only fully override the backing file options
113 # if you either specify a node reference (as done here) or the new
114 # options contain file.filename (which in this case they do not).
115 # In other cases, file.filename will be set to whatever the image
116 # header of the overlay contains (which we do not want). I consider
117 # this a FIXME because with -blockdev, you cannot specify "partial"
118 # options, so setting file.filename but leaving the rest as specified
119 # by the user does not make sense.
