In this context I don't think the version matters though. The original
question was why we are focusing our test efforts on Ubuntu and CentOS,
and the answer is that ~90% of our users are on those platforms. The
specific version they're on right now doesn't really matter - even if
they're on an older one, chances are eventually they'll move to a newer
release of that same OS.
