I have been able to get Unicorn to start up properly with my Rails 2.3 app on Heroku's Cedar Stack, however, it is not serving the static assets correctly from the public folder. I have tried placing this line in our config/environments/production.rb:
config.serve_static_assets = true
But then our app fails to load properly. Without it, the app boots fine, just doesn't serve the static files. Is that line of code not compatible with Rails 2.3?
One note for people with the same sort of config, make sure to create a config.ru in your app root.
