Okay it looks like what is happening is the triggers are used when 
plugins are installed, and the CentOS 7 way is to run those triggers in 
the post/pre scriptlets of the packages that have the plugins.

Probably better to have the file trigger conceptually, less chance for 
scriptlet bugs, but CentOS 8 will come soon enough I suppose ;)
