I hate config files

I hate config files. There, I said it. Made a change to your configuration? Database? Temp location? Gotta redeploy your application. Even if you have an awesome deployment mechanism it just seems somehow wrong to have to redeploy your app to make a configuration change. From a security standpoint, I don’t particularly like having passwords and such being stored in a source repository. Or making it part of your build process. Or manually editing files in production.
