latest head ( 6db0c70521e1abb520481535b1632fc8611a8030 ) doesn't work for me

Heads up. I have an automated build that has used this repo for a long time. It just broke against
6db0c70
rolling back to 8b5e0fc seems to work fine.
I notice that at a minimum there is an issue with the current README's "example script to leverage instance storage" which has a space in the middle of the else clause making it "--mount point" instead of "--mountpoint" as well as a seemingly new IAM role requirement for "ec2:DescribeInstanceTypes" when using the instance_storage_checker.sh.
