The only way you can do that is by removing any dependencies between the resources, e.g. attributes or chaining arrows.

However, the better question is: why do you want to do this, and under what circumstances? If resource A truly requires resource B, then how can you apply resource A if resource B fails? If it doesn't matter, then there's no dependency between those resources.

If the service doesn't depend on anything else on your system, you don't need to create dependencies on it. NB: If you can't start the service by

what Greg said . .. but just to add to it - the puppet DSL isn't about running a set of commands per se but about defining the end state you want to achieve - so from that point of view you need to specify dependencies (or none - as it appears in this case)
