No. You can assume that puppet will specifically *NOT* do that.
Puppet has an internal dependency system that it uses to apply a partial
ordering to the entire set of things it has to do.
So, anything that you specify an explicit dependency for, or that has an
implicit dependency[1], you are guaranteed that puppet will do them in the
order you specify — or will fail if there is no order that works.
For everything else you can assume that the order is absolutely, completely,
totally random, and that the random order *changes* every single run.
