Linux distro done by Oracle?

This is not first time that I've heard Oracle speaking about build their own operating system. In fact, there're people that considers they got a lot of job already done. For instance, you may writte your tablespaces in a raw device, which is, writting without operating system, and delegate to Oracle software this task, instead of instruct your OS, Oracle does it for you.

... but keep in mind, that Ellison were talking about I'd like to have a complete stack ... so he was talking just about a it may be.
