That depends on what you mean by "really copying it". If you copy with --sparse=always and the file has at least one non-sparse run of zeros, that result will be smaller than the cloned file. >> Adding this optimization should not change the meaning of >> --sparse=always. > > So do you want to use it only when --sparse=auto is used?
