Standard file locations and permissions

edit

With askbot running on Apache/mod_wsgi, what locations do you use for its folders, such as

• /path/to/askbot (the git/site-packages folder, needed for server media location /m),
• /path/to/django-project/askbot (the one from askbot-setup, used in server /upfiles),
• django-project.wsgi used in WSGIScriptAlias?

Connected to that, how do you handle server updates (production site vs. sandbox)? What do you put under DocumentRoot? What permissions do you give to other users (such as user www-data)?

EDIT: Just to clarify -- my installation works fine, I am only looking for practical recipes on how to manage the installation properly, and in standard fashion. Thank you :)
