RE: Instance-store Amazon AMI
In CloudFormation, against your instance (or Launch Configuration if using AutoScale), use:
"BlockDeviceMappings" : [ { "DeviceName" : "/dev/sdf", "VirtualName" : "ephemeral0" } ]
And in your UserData, you may want a script to test the volume for a partition, and if empty do a format and mount.
