Pass the layout param for devise

Is there a way to tell devise to use a specific design, not the layout/application.html.erb ?

I thought I could create a controller class like:

class DeviseController < Devise::SessionsController
  layout 'devise'
end

with a routes like:

devise_for :users, :controllers => { :sessions => "devise" }

but this doesnt work, it gives me a 404.

Shouldn't the extends responds to the methods?

After 2 more minutes I found the answer myself...

Just add the layout as sessions.html.erb
