Oracle may never "certify" CentOS, but we, as a community of users, can share enough
information to build a similar level of trust. My own opinion is that too many people
have worked for free for too long on Linux to have it ever become a proprietary platform.
So, Please use this thread to tell others:
How you are using CentOS and Oracle? Are you using machines in production?
How many machines, and for how long?
If you installed both on RedHat and on Centos, did you find any differences?
