is that it defaults to a more modern and appropriate kernel version
(which is part of this beta). Before this, we were only able to run
against the kernels published by Amazon, but Canonical has worked out a
relationship which lets them build custom Ubuntu kernels for EC2 (and
has put in the hard work to build them).
Insofar as I continue publishing community AMIs after the official
public release, I expect to use the new official kernels with the

in flux and you can easily install any you find to be missing.
- The beta only supports Intrepid server.
I expect to eventually phase out support for many of the community AMIs
I build in favor of the official Ubuntu images, though this could take a
