Yup the yum manifest sets up my configuration files for the various repos
(ie, we have a development repos for our lab that only goes on lab systems
and production hosts the production repo).

Package { require => Class["yum::base"] }

I guess I could put that in every manifest at the top that is doing package
installs.  Is there one place I could put this so it applies to ALL modules,
perhaps site.pp?
