It seems to me that most people have a class or a set of classes that they like to have applied to all of their systems. I think it would be great if foreman could provide a way to have this.

For me personally I just need to have the ability to apply 1 class to all systems, but I could see having additional functionality being advantageous. What I mean is maybe adding a default class based on:

1) OS
2) Some fact value

Adding logic could make it more difficult to implement, so I would say for now just a way to assign a collection of classes to all systems would be great.

Previously to support this functionality I was defining those classes in my site.pp, but it would be better to have the ability for the ENC to be a single source if used. Currently I'm 'hacking' this functionality with the attached patch (based on 0.4).
