Thanks for all of the replies on this topic.
I should clarify that I am not as concerned about minor
glitches in the actual Fedora Core releases but rather
being able to get timely security updates without de-evolving
a machine installed with Fedora Core to a test release.
It seems this is unlikely to be avoided.
I will probably just purchase academic licenses for
RedHat Enterprise Linux but I would note that RedHat
doesn't go out of their way to help you find them on
their web site. Also, I am still a bit concerned about
the degree of forking RedHat has introduced with this
release strategy. Before they had become the reference
release and scientific software was often marked as
compatible with a certain RedHat release. Now with
Fedora this has become a murky target.
