[chef] Re: Changing the order of 'run_list'

[Noah Kantrowitz < >]

This is not something you should generally do as changing the run list from 
inside recipe code probably won't have the effect you expect. Notably it 
won't have _any_ effect until the next run assuming the current one succeeds.

As to your specific question: 
node.run_list.run_list_items.insert(node.run_list.find('role[base']), 
'role[web]'). You can find more information in the Ruby documentation for 
Array#insert and Enumerable#find.
