In my _personal_ utopia of the industry smile-tests are worthy; I do
however realize business is business and people want stable yet affordable
solutions before anything else. That said, smiles can be had along the

It all comes down to opportunity cost; time spent working with the Fedora
project (and its evolving policies) to add required features is
time consuming and takes away from _real_ HPC innovation. BUT, if the
entire HPC community actually worked together to bring about that change
it wouldn't be that hard. Too idealistic? It would appear so based on
the resounding cry for rebuilt RHEL solutions. Keep in mind that
customers want "the real thing".

It comes down to the unfortunate reality that many in the HPC community
would rather continuously fork/reinvent RHEL than work with Red Hat to
arrive at a mutually beneficial arrangement.

While I appreciate you associating myself and my views with my employeer I
have expressed my _personal_ views. However, your assessment of my
employeer's focus is not accurate; but I'm not going to get into that

Make no mistake about it, its not good for any commercial company that
historically relied upon Red Hat Linux; hence the extensive attention this
debate has recieved all over the Internet. You have blantantly attempted
to spin this thread in a self-serving/tangential direction of company<foo>
vs company<bar>; and it wasn't about that. Now I know why this list is
perdominantly technical and _tries_ to stay away from the commercial
interests of any one vendor.
