This occurs when the task depends on multiple files and the sort order of their paths changes. Usually the sorting is consistent because layers tend to have the same relative paths, but this should take care of other configuations. The problem arose when using a .bbappend to add files to a recipe in another layer. If the layer is located alongside the other layers and their parent directory is moved, the hash does not change. However, moving the .bbappend layer outside of the common directory can change the path sort order and the task hash.
