It might be too late posting about Oracle Linux 7 (Beta 1). Just came back from long holidays in Thailand. I think it's very interesting to learn something new in OL7. Users can download it by using OTN account.
Download.
Release Note.

After installed it, I tested some a little bit.

[root@ol7beta ~]# cat /etc/oracle-release
Oracle Linux Everything release 7.0 Beta
[root@ol7beta ~]# uname -r
3.8.13-31.el7uek.x86_64
Users can choose to start with RHCK or UEK3.
[root@ol7beta ~]#

Oracle Linux 7 provides the temporary file system (tmpfs), which is configured in volatile memory and whose contents do not persist after a system reboot.

Note: After installed, Not found "ifconfig" command line.

[root@ol7beta ~]# ip addr

The output of the ifconfig command has changed format.
So, installed ifconfig command and tested.

Oracle has released the Unbreakable Enterprise Kernel for x86_64 servers via the Oracle Public Yum Server. We can review Oracle Linux features.

Ensure that your system is running Oracle Linux 5 Update 5 (x86_64) before installing the Unbreakable Enterprise Kernel.

But I tested on Enterprise Linux Server release 5.4. (just test ^ ^)

# cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.4 (Carthage)

# uname -a

That is on Enterprise Linux Server release 5.4, then tested on Enterprise Linux Server release 5.5

Steps:
1. Ensure that your system is running Oracle Linux 5 Update 5 (x86_64) before installing the Unbreakable Enterprise Kernel.
2. Download and install the Oracle Linux 5 repo file to your system.
# cd /etc/yum.repos.d
# wget http://public-yum.oracle.com/public-yum-el5.repo
3. Enable both the [el5_u5_base] and the [ol5_u5_base] repositories in the yum configuration file by changing enable=0 to enable=1 in those sections.
4. To update your system kernel to the Unbreakable Enterprise Kernel, use the following yum command:
# yum install kernel
OR To upgrade all recommended packages associated with the Unbreakable Enterprise Kernel, use the following yum command:
# yum install oracle-linux
5. Reboot your system to run the newly-installed Unbreakable Enterprise Kernel.

Start to Test on OEL5.5:

# cat /etc/enterprise-release
Enterprise Linux Enterprise Linux Server release 5.5 (Carthage)

# uname -a
Linux oel 2.6.18-194.el5 #1 SMP Mon Mar 29 22:10:29 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

After I updated Kernel... It can mount btrfs, that is good.
