Oracle Linux 7 Released Today As Its RHEL7 Clone
With the Oracle Linux 7 release they continue to claim they are "the only major enterprise Linux distribution that publishes all bug fixes and security errata publicly, providing more flexibility and choice than other commercial Linux distributions."
Oracle Linux 7 has all of the same exciting RHEL7 features like XFS by default, various virtualization and cloud improvements, etc, along with Oracle's few originals like Ksplice and the Unbreakable Enterprise Kernel flavor. For most people though if not up for paying for Red Hat's costs, you'll be better off with CentOS 7 or Scientific Linux 7.
