Strange... It got totally lost from my memory :-(

Perhaps I got mislead by the web interface on Savannah pointing to a
(non-existant) hurd.git instead of hurd/wiki.git...

Why does it need to scribble over it?...

Ah well, this is really a question for the ikiwiki developer, and rather

That would be a rather radical solution...

I'm not sure how else it should behave.

One possible approach would be to have a hook in the external
repository, checking before every external push that it's in sync with
the internal one...

Of course, this would still be problematic, when the internal repository
is not reachable...
