Making a Boot from EBS Volume

Making a Boot from EBS Volume - These instructions don't work

#!/bin/bash

# Go to console.aws.amazon.com
#   - launch a spot instance of one of alestic's images (see alestic.com)
#   - create a 5G EBS volume
#   - attach the 5G EBS volume to your instance
#   - log into the instance with ssh

set -e -x 

EBS_DEVICE=/dev/sdf

mkfs.ext3 /dev/sdf
mkdir -p /emph
mount /dev/sdf /emph
rsync --stats -av --exclude /root/.bash_history --exclude /home/*/.bash_history --exclude /etc/ssh/ssh_host_* --exclude /etc/ssh/moduli --exclude /etc/udev/rules.d/*persistent-net.rules --exclude /var/lib/ec2/* --exclude=/mnt/* --exclude=/proc/* --exclude=sys --exclude=/dev/shm --exclude=/dev/pts --exclude=/selinux --exclude=/lib/init/rw --exclude=/tmp/* --exclude=/emph / /emph

# edit /emph/etc/fstab to mount /dev/sda

umount /emph

# Go to console.aws.amazon.com
#   - detach the volume
#   - create a snapshot of the volume

# now install ec2 tools to register the image

curl -o ec2-api-tools.zip 'http://s3.amazonaws.com/ec2-downloads/ec2-api-tools.zip'
unzip ec2-api-tools.zip
cd ec2-apu-tools-1.3-*
apt-get install sun-java6-jre
export JAVA_HOME=/usr/lib/jvm/java-6-sun 
export EC2_HOME=$(pwd)

$EC2_HOME/bin/ec2-register --snapshot snap-410b2f28 --description="Debian Squeeze" --name="Debian Squeeze 0001" --architecture i386 --root-device-name /dev/sda

This didn't work. The AMI was not able to boot, it had not console output.
