[ec2] disk partition configurations

[Darren Govoni]

Hi,
  Pardons if this is a more general question, but I am running the 8.10
beta1 on high-cpu instances. I notice the drives are partitioned more or
less into 3GB partitions. 

  I see the /mnt is 400GB but its not part of the image.

  Is there a way to specify that I need say a 500GB drive and at least a
200GB partition somewhere that gets bundled into the image? I can't use
EBS or /mnt because I want some data burned into the image that is about
120GB in size.

Is it possible?

thank you,
Darren
