I've made a few OS's from the the CentOS 6 base images in AWS, and they're working quite wwell. But I'm reaalizing that they do not have the enhanced networking enabled by default. And I'm also realizing that I have to *stop* the OS in AWS terms, enable network enhanced networking manually, and lose all the contengs of my ephemereal storage when I do this.

Is there any reason not to enable enhanced networking by default, in the base CentOS 6 image and same a painful and painful step for AWS users?
