[ec2] error when moving Home folder to persistent EBS

[Rodney T. Quillo]

Hi Pedro,

> Issue #1 : sudo: cannot get working directory (after ln)
You are at /home/ubuntu directory when you did the mv command. Try cd to  root 
directory or /mnt then execute: 

sudo mv /home/ubuntu /persistent/home/ubuntu
