Does cloning a shallow repo require special setting in the cloned one?

Hi,

I have a question about cloning shallow repo.

$ git clone --depth 1 git://git2.kernel.org/pub/scm/git/git.git git-shallow ok, 'git log' gives a 2-revision history.

$ git clone git://git2.kernel.org/pub/scm/git/git.git git-full 'git log' gives a full history

$ git clone --depth 1 git-full git-shallow2 'git log' still gives a full history

Why can't I clone a shallow repo from the git-full? Does it requires some settings in the git-full repo?
