F24 is set to release on June 7, docker makes a major release each
three months or so, and 1.9 is already three months old... 

I don't think it's possible to fully shield users from the fast dev 
pace of docker while keeping fedora reasonably up-to-date. 

Docker just moves fast, we should kick our testing into a higher
gear to keep up.
