Explain the difference between a singleton and non-singleton type:

A single type can only be used once per host.

(I don't see yet why this is important.)

Reference

If a type is flagged as a singleton, it may be used only once per host. This is useful for types which can be used only once on a system. Singleton types do not take an object name as argument. (https://www.cdi.st/manual/latest/cdist-type.html?highlight=singleton)

Explain the difference between the different verbosity levels

Verbosity levels are used to change the amount of information that is output on stdout about the configuration run. I can be used for debugging, monitoring and scripting.

Comment out __my_nginx from the initial manifest, keep the __my_nginx_site

  • Explain the error that you get (in your cdist.org file)

The manifest __my_nginx wasn't run (or marked as completed) which haven't fulfilled the requirements for __my_nginx_site
