[Beowulf] HPE to acquire Cray

I just wanted to point out that Fedora, while having a lot of volunteers is
primarily driven by Red Hat employees, so I don't think forking it is a
viable option. If you want to get an idea of what forking RHEL/Centos would
be listen to an Oracle Linux rep who will be more than happy to tell you
how much trouble they have untangling Red Hat's obfuscated kernel blobs.
Red Hat invests a lot of money to keep their ancient franken-kernels
running. I heard it took on the order of 5000 man hours to backport
Spectre/Meltdown patches to RHEL 6.

 Also this just what was given up when they announced the end of Scientific
Linux recently, so if that's what anyone is thinking I think it makes more
sense to reach out to them to see what it would take to keep that going.

I wish that Debian was the default choice since they can't be bought and
every other commercial Linux entity is financial precarious, which makes
them less reliable than Red Hat to me. I don't doubt that it's doable but
it would have to be the norm for a lot of us to start doing that since so
much of the HPC specific tooling seems to be targeted to RHEL/Centos/SL.

I had the same concerns regarding Centos, but I feel we're save in the near
term and if it does start go sideways it will happen slowly enough that
there should be enough to time to figure something else out.
