Deterministic Catalog Application¶

Previously, Puppet didn’t guarantee that it would apply unrelated resources in any particular order. This meant that if you forgot to specify some important before or require relationship, a single catalog might work fine on eight nodes and then fail mysteriously on the ninth and tenth. This could be frustrating! Now it’s gone: Puppet will make sure that the same catalog will always be applied in the same order on every machine, and it’ll either succeed reliably or fail reliably. (This change will also be appearing in the final 2.6.x releases.)
