I deployed an app to AppFog. on their Env Variables, I placed "FUEL_ENV" => production.
getenv() is properly detecting it. However, it looks like FuelPHP still isn't running as production.
The config on production/db.php is not detected, however, development/db.php is. I noticed that when I placed SetEnv FUEL_ENV production on .htaccess, it works. (But of course, that's not how we're supposed to deploy it to the cloud).
