If it's what was on the PHP Fog Sucks website, it worked something like this (I may be misremembering a step): 1. Use the post-deploy hook to chmod /home/ubuntu/.ssh so that it could be written to. 2. Upload a PHP shell, use it to write your public key into /home/ubuntu/.ssh/authorized_keys, and get the public IP of the EC2 instance. 3. SSH into the box, sudo su will get you root.
