Rails 3 initializers that run only on `rails server` and not `rails generate`, etc

Question

I have a relatively small piece of initializer code that I want to run whenever rails server runs, but not when I run rails generate, rails

Answer 1

Can you do something like overriding Rails::Server#initializeso that it invokes your initialization code in your initializer?

Or, more easily, just put your code in script/rails, as that will be run everytime you run rails server, you can easily fiddle with ARGV or ENV in there.
