Hello,
how do I configure a git repository in a way, that no modifications of
existing history (eg "commit --amend", "branch -d", "rebase") are
allowed?
Regards, walther

From the git-config man page

       receive.denyNonFastForwards
           If set to true, git-receive-pack will deny a ref update which is
           not a fast-forward. Use this to prevent such an update via a push,
           even if that push is forced. This configuration variable is set
           when initializing a shared repository.


so set that variable to true. This has to be in the repository you use
to synchronize. IIRC it can't be avoided locally (but that's not a
problem, because you shouldn't be working directly on the public repo
anyway).

Cheers,
