Greetings all - just wanted to let you know I made a couple tweeks to the very very simple, very non-professional, non-bulletproof "createfedorabootebs.sh" script.  You can find slightly longer instructions here:

https://fedoraproject.org/wiki/Publishing_image_to_EC2

The steps are relatively simple.

1)  create an instance from the official AMI (or anywhere else, really)
2)  create a new volume, whatever size (at least 2g or so) and mount it at /dev/sdf
3)  run the createfedorabootebs.sh script
4)  snapshot the volume
5)  register an AMI with the snapshot and the pvgrub hd0 aki

It's a simple script; even a novice can tell what is going on.  The sources are all from Fedora, and nothing funny is happening.   This is the low-speed, "I don't know boxgrinder, I don't have a machine I can run xen on anyway, I want to know what is on the image" approach.

That said, I *heartily* recommend using jforbes' AMIs instead; he'll have EBS-backed AMIs soon, I'm sure.  This is only for those who want to play, or need an ebs image today.  Or, if you're really crazy, it's for people who want to look at getting rawhide on ec2!
