AMI build script
Anders Ingemann has created a build script for bootstrapping instances like the above. The script runs fully automatic and needs no user interaction, custom scripts can be attached to the process as well. You can download or clone the script on github. Any bugs or suggestions should be reported via the github issue tracker.

Security of user-contributed AMIs
Please consider the security of user-contributed AMIs as having been potentially untested and un-vetted by the Debian Project. Always check the AMI ID matches what you were looking for, and verify the AMI Source to confirm the AMI you are launch is being updated and controlled from an account ID that you trust.
