If you add a dir directly under app/

Do nothing. All files in this dir are eager loaded in production and lazy loaded in development by default.

If you add a dir under app/something/

	Managing Amazon EC2 - SSH login and protecting your instances

	How to log into your freshly fired-up instances and how to secure ssh access
	(works under Linux and Mac OS, under Windows with Cygwin)

	First time you want to log into a newly started instance you appear to have the chicken-and-egg problem: how to log in when you do not know the root password? Luckily Amazon devised a comfortable way to circumvent this: your Key Pairs. these are not to be confused with the „Access Key IDs“ on the Access Identifier web page and they are neither the X509 certificates. These Key pairs are automatically generated the first time you log into the web console and you can only download its private part. Store it in your ~/.ssh directory. In case you missed the download or don't know where you've put it AND you don't have any instances running, just generate and download a new one.
