Once again, the problem seems to be hatred of Ellison more than anything else.

Red Hat and CentOS based on it are #1, it´s only natural that smaller
players want a piece of the pie.

This is different from Novell trying to lure RHEL users exactly how?

What Oracle is saying is "if you want free, you can use ours instead
of CentOS and get a more recent kernel"

centos 6.3 -2.6.32-279.1.1.el6

Oracle distributes Oracle Linux with two kernels:

    Red Hat Compatible Kernel - identical to the kernel shipped in Red
Hat Enterprise Linux (RHEL).
    Unbreakable Enterprise Kernel - based on a later Linux 2.6-series
kernel, with Oracle's own enhancements for OLTP, InfiniBand, and SSD
disk access, NUMA-optimizations, Reliable Datagram Sockets (RDS),
async I/O, OCFS2, and networking.[8][9]


New Btrfs features/functionality

    An updated version of btrfsfsck, a tool to check and repair a
Btrfs file system, is now included in the btrfs-progs package. This
new btrfsck now supports a --repair option that allows fixing errors
in the extent allocation tree and block group accounting. btrfsck also
provides the option --init-csum-tree which replaces the check-sum root
with an empty one. This will clear out the CRCs but allows the
file-system to be mounted with the mount option nodatasum.

    Automatic defragmentation: Brtfs now provides an online
defragmentation facility that reorganizes data into contiguous chunks
wherever possible to create larger sections of available disk space
and improve read and write performance.


Xen domU improvements

Several bug fixes and improvements have been incorporated to make the
Unbreakable Enterprise Kernel scale and cooperate better as a guest
(domU) in Oracle VM and Xen.

    Xen block backend from Linux 3.3 kernel. This provides the fully
featured Xen blkback along with extra features, such as passing
through a flush (a lighter version of barrier), discard (also known as
TRIM or SCSI UNMAP) and various bug-fixes and enhancments.
    Xen PCI backend from Linux 3.3 kernel, this includes the option to
specify how the PCI structure shows up in the PV guest - either as in
host or virtualized; Fixes to make it work with SR-IOV VF cards; and
numerous mutex fixes.
    Memory self-ballooning - allows the guest to automatically balloon
depending on the workload.
    Transcendent memory support for HVM and PV guests
    Tracing API support for Xen MMU operations.
    Syncing the wall-clock time from the initial domain
    Numerous code cleanups and bug fixes (e.g. in the following areas:
memory balloning, blkfront, P2M, E820, IRQ, MMU, Gntalloc driver)

Other improvements

    dm-nfs: device-mapper target that allows you to treat an NFS file
as a block device. It provides loopback-style emulation of a block
device using a regular file as backing storage. The backing file
resides on a remote system and is accessed via the NFS protocol.

Driver Updates

The Unbreakable Enterprise Kernel supports a vast range of hardware
and devices. In close cooperation with hardware and storage vendors,
several device drivers have been updated by Oracle. The list below
only indicates the updated drivers that deviate from the versions
included in mainline Linux 3.0.16.
Storage drivers

    Broadcom bnx2i
    Broadcom bnx2fc 1.0.4
    Brocade bfa
    Emulex be2iscsi
    Emulex lpfc
    LSI mpt2sas
    LSI megaraid_sas 5.40-rc1
    QLogic qla2xxx
    QLogic qla4xxx

Network drivers

    Broadcom bnx2 2.1.11
    Broadcom bnx2x 1.70.00-0
    Broadcom cnic 2.5.7
    Brocade bna
    Cisco enic
    Emulex be2net 4.1.297o
    Intel e1000e 1.4.4-k
    Intel ixgbevf 2.1.0-k
    Intel igbvf 2.0.0-k
    Intel ixgbe 3.4.8-k
    Mellanox mlx4_en
    QLogic netxen_nic 4.0.77
    QLogic qlcnic

Sounds like value-added to me, for those that need that functionality.

For those that do not, CentOS is just fine.

The OP got the negative reactions he came seeking, I bet...
So can we please move along?. This bickering and gnashing of teeth
does nobody any good.
