# Build a Linux EC2 AMI
# For RPM based distributions


# Based on the this wonderful tutorial, thanks Phil!

    ## Features

# Can build instance store or EBS backed AMIs from scratch
# Can use YUM repos from build host or distro default


# Must have access to any YUM repositories specifed

    ## Create Instance Store Backed AMIs

# Set "EBS=0", and set "ROOT" to be a local filesystem location large enough
# to hold your AMI, which can be 10GB max size.


    ## Create EBS Backed AMIs

# EBS volumes must be built on a EC2 instance.  Once built, snapshot and
# register the EBS volume as an AMI.

# Attach an EBS volume of desired size to a running instance.  Set "EBS=1",
# and set "ROOT" to be the mounted EBS volume.
