From the Flame War! dept.:
Redhat has gone on the offensive against Oracle introducing a promo sneakily named Unfakeable Linux:

..."Q: Oracle says their Linux support includes the same hardware compatibility and certifications as Red Hat Enterprise Linux. Is this true?

A: No. Oracle has stated they will make changes to the code independently of Red Hat. As a result these changes will not be tested during Red Hat's hardware testing and certification process, and may cause unexpected behavior. Hence Red Hat hardware certifications are invalidated.


...Q: Will Oracle's product result in a "fork" of the operating system?

A: Yes. The changes Oracle has stated they will make will result in a different code base than Red Hat Enterprise Linux. Simply put, this derivative will not be Red Hat Enterprise Linux and customers will not have the assurance of compatibility with the Red Hat Enterprise Linux hardware and application ecosystem..
