We recommend using the attributes files in the cookbook simply for
setting default values.

default[:shorewall][:rules] = []

So they don't cause nil errors when accessed elsewhere.

Then you can use the recipe to do a search, generate the rules as
hashes (per your code example, but assign to generated_rules), then
something like:

node.set[:shorewall][:rules] = generated_rules

Near the end.
