Looking at it, if I'm correct CentOS is the only "free" OS on there
(with 8 installs).  I'm guessing that if you've got the $$ to build a
top 500 computer, you're willing to pay for a service contract on  your
OS to better keep it running.

On the other hand, what the heck is "Linux".  Looks like they weren't
very consistent in their naming methodology.  There's also "Red Hat
Linux" by itself as well as broken into RHEL4 and RHEL5.
