Find a way to make it work with an existing Piwik install

[mnapoli]

I've been trying to use the Vagrant box with my Piwik install, but with no success until now.

piwik/
    # contains Piwik code
piwik-dev-environment/
    ...
    www/
        piwik/ # hey Piwik is cloned here again

I've tried symlinking piwik-dev-environment/www/piwik to the existing Piwik install but VirtualBox doesn't like that (since the simlinked repo is outside of the VM).

How do you do it yourselves?

Should we consider merging that in Piwik's repo? I'd love (and I guess users too) to be able to do just git clone and vagrant up on the Piwik repository.
