		<description><![CDATA["There is more than one way to kill a cat", though I haven't killed a cat since birth. And so, there's another way of mounting EBS volume from boot startup. It's possible to replace the default volume ID by passing user-data script when launching the instance.

Requirements:
   AWS accesskey and secret keys
   Tim Kay's <a href="http://timkay.com/aws/">aws</a> tool.

Tested using Ubuntu 9.10 Karmic  AMI: ami-1515f67c

How to install the script: 

1. Copy the script to at /etc/init.d/mount_ebs_override
2. Replace the default volume vol-xxxxxx in the code.
3. Change the script to have executable permission.
4. Copy access and secret key to /root/.awssecret separated by a newline.
5. Change file mode of /root/.awssecret to 600 
6. Run update-rc.d:  update-rc.d mount_ebs_override defaults 89
7. Bundle the AMI. :)

When the new AMI is launch without value on the user-data, it will mount the default volume ID provided on the script. In order to use a different EBS volume, add the OVERRIDE_EBS_VOLUME=volume-id as value for the user-data and launch the instance. 

Note: Just make sure the instance is launch on the same zone of the EBS volume.

The release of AWS share EBS snapshots
How to Boot EC2 Instances from EBS
Cool Things You can do with Shared EBS
Hidden Dangers in Creating Public EBS Snapshots on EC2

Using the references above I tried to test Bootable EBS volumes, I’ve made some experiments (duh) to test bootable EBS volumes base on Alestic AMIs:
Ubuntu Hardy(ami-e546a78c)
Debian Lenny AMI(ami-ff46a796)

Note that both of these AMI’s are using the same AKI (aki-a71cf9ce) and ARI (ari-a51cf9cc). Therefore the two boot EBS volumes created has this properties. To create the Lenny and Hardy bootable EBS volumes, I simply follow Shlomo’s How to Boot EC2 Instances from EBS tutorial.]]></description>
