> My understanding is that Container Linux as is will be supported for years, but we will also be creating a new distro, RH CoreOS, that replaces the Gentoo build system with Fedora tooling.

As a Gentoo dev and long time user, I've always had a lot of sympathy for CoreOS since the beginning, so when I heard about the RedHat acquisition, I wondered about this. I have to say that I'm saddened to know that Portage will be eventually replaced. It's an excellent package manager.
