If I use an AMI like this, can I successfully replace the kernel and have it boot properly? If so, sure, I'd love to see it, but note I will probably not be able to do anything with it until late next week due to the holidays here. > > Hm, no, I _wish_ I could build in one minute on an EC2 image, right now > > it's about 5 minutes, as you have found.

I'll play around with that idea later next week if I get the chance. Although I can't imagine what the cost will be for doing something like this, pretty soon it will just make more sense to buy a real box and use it instead of the cloud :) thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
