Because we deploy by updating an existing environment the default
sprockets strategy gives us multiple randomly named manifest files
and it will then pick one arbitrarily when starting up.
# Version of your assets, change this if you want to expire all your assets.
Rails.application.config.assets.version = "1.0"
+# Location of manifest file.
+Rails.application.config.assets.manifest = Rails.root.join("tmp/manifest.json")
+
# Add additional assets to the asset load path
# Rails.application.config.assets.paths << Emoji.images_path
