-        It does not guarantee that the image will be installed into the
-        specified slot, but does guarantee that, if the slot is empty, no
-        image will be overwritten, and if the slot is not empty, no image
-        other than the one in that slot will be overwritten.

-        The method will fail if either of the identifiers is invalid, or if the
-        image could not be installed into the slot for some reason.
