From 

http://docs.opscode.com/resource_ruby_block.html

The ruby_block resource is used to execute Ruby code during a
chef-client run. Ruby code in the ruby_block resource is evaluated with
other resources during convergence, whereas Ruby code outside of a
ruby_block resource is evaluated before other resources, as the recipe
is compiled.
