About every 30 minutes.  This is configurable but I've never known us to 
override it.

Nope!  puppetmaster::self causes puppet to use the local files in 
/var/lib/git/operations/puppet (aka /etc/puppet) rather than the 
official puppet files and manifests.  Once a change has been merged it 
becomes part of the official set and is applied to all systems.

The configuration of self-hosting systems will lag behind since they are 
still using their local manifests and are more-or-less unaware to the 
official manifests.

Modules are the future!  Manifests that stand outside of modules are 
legacy code which will (someday) be refactored into modules.

If you're altering existing puppet code and don't have grand refactoring 
ambitions,  you should just edit whatever is there now (manifest or 
module).  If you're building a new feature, you should dive in and make 
a module.

I am pretty sure (but not positive) that modules/mediawiki_new is meant 
to be used for production mediawiki installation (and deployment-prep).  
The single-node manifests you've been working on are specifically 
intended for labs prototypes and demos; it's unlikely that the two will 
ever converge.
