I haven't been working on one, but dzz has, and it's mostly identical to the wheezy version of refracta.
See this post and the next page of that thread -
going-with-the-systemd-flow-or-not-t422-130.html#p4815I believe there will eventually be an official refracta8 release, but I can't say for sure when. If you're not concerned about systemd libs in your installation, it would be fairly simple to turn the existing jessie-sysv isos into a build that's close to the wheezy refracta. I think it's just a matter of un-pinning some packages, update/upgrade and then install a list of packages. If you're interested in doing that, I could provide details. Some of it was scripted for squeeze and then wheezy, and some parts are still relevant.
And if you don't want any systemd libs, then right now, dzz's build is the best choice, but be aware that it's still experimental.
