rake rails:update:configs question

I have an 2.0.1 application and just updated rails to 2.0.2.

Then i cd'ed to an applications directory and edited config/environment and changed

RAILS_GEM_VERSION = '2.0.1' unless defined? RAILS_GEM_VERSION

to

RAILS_GEM_VERSION = '2.0.2' unless defined? RAILS_GEM_VERSION

and run rake rails:update:configs from the console.

What files should be touched by this command?

Only config/boot.rb?

I thougth this command also will touch config/environments/production.rb

to get this new standard set:

config.action_view.cache_template_loading = true
