Puppet manifests do not run in a top-down manner, but instead run
semi-randomly. Because your file and exec resources need to run in a specific
order, you need to define that order specifically. You can accomplish this by
keeping the order you have and simply adding a 'require' parameter to each that
points to the previous resource.
Even better would be to convert the entire thing into a single package/rpm that
you keep in a repository and have puppet install it with a single 'package'
resource.
