Comment 5 for bug 1415240

I'm inclined to say that we should probably define some min/max versions
for each distro that we build and state those in the README of the distro
element. Then, ideally we could make some basic CI jobs that build and
test those versions and exercises package installs, source-repositories,
etc.

As of now the closest thing we have to that is the tripleo-CI which
tests Ubuntu 14.04 and Fedora 20.
