I'm not sure if you'll want this one (though it's definitely the way I went with it when I just provisioned my machine), but it switches the bash installation method to use homebrew's bash and switch the user's shell to use it.
I will not merge this, i've had issues in the past with bash compiled from homebrew. The bash.rb recipe is "needed", but upgrading the bash version is not. As a separate recipe however i will merge this.
