the git repositories of the OCA (https://github.com/OCA/hr for example) are contain always a bunch of modules, so if you clone them with git you get a folder with subfolders.
The 'addons_path' in your config file can not handle such a 2-level structure, so if you clone into the 'addons' folder Odoo will not find these modules. Is there any common practise how to organize that best?
Just adding level-1 folders in /opt/ocb/ocb-server for each batch of modules and then extending the addons path seems a little cluttered, isn't it?
