EC2 doesn't lend itself well to kernel updates.  EBS-backed instances 
aren't really problematic because one only needs to update kernel 
packages, stop the instances, change kernels+initramfs images to newer 
ones that Fedora has presumably already made available, and then restart 
them.

Instances that don't have EBS-backed root filesystems can't be stopped, 
and termination destroys them utterly.  So one has to either rebundle 
Fedora's image as one backed by EBS or start up a new instance with the 
new kernel+initramfs, move everything over, then terminate the old one.
