Major Description
Hi,
I was trying to use the spark-ec2 script from Spark to create a new Spark cluster wit an user different than root (--user=ec2-user). Unfortunately the part of the script that attempts to copy the templates into the target machines fail because it tries to rsync /etc/* and /root/*
This is the full traceback
rsync: recv_generator: mkdir "/root/spark-ec2" failed: Permission denied (13)

Is there a workaround for this? I want to improve security of our operations by avoiding user root on the instances.
