Seems to work, but still experimental until it's been tested more. When repositories are on filesystems not supporting symlinks, the .git dir symlink trick cannot be used. Since we're going to be in direct mode anyway, the .git dir symlink is not strictly needed. However, I have not fixed the code that creates new annex symlinks to handle this case -- the committed symlinks will be wrong. git annex sync happens to currently fail in a submodule using direct mode, because there's no HEAD ref. That also needs to be dealt with to get this fully working in crippled filesystems. Leaving http://github.com/datalad/datalad/issues/44 open until these issues are dealt with.
