Rebase needs to create new commits for two reasons: 1. Each commit contains a reference to its parent(s), and hence indirectly to its entire prehistory, and 2. When you rebase, you are essentially applying diffs corresponding to the commits you are =E2=80=9Cmoving=E2=80=9D to other commits, so t= he rebased commit will refer to files that are different from the ones before the rebase. =E2=80=93 Harald
