Try subscribing and waiting on the next set of changes.  We did, but
didn't have enough time to wait long enough.  YMMV (read: they may
have changed).

I presume it is because of the length of testing they do based upon
the presumption that Oracle SW is involved at the user's site.

There's one *very* big difference, which should be kept in mind: CentOS
doesn't spit on Red Hat.

ok, you seem confused and seem to be buying into the marketing that 
oracle sends down the line. The 1 major difference is that CentOS really 
is binary compatible with upstream RedHat. Oracle isnt. They ( oracle ) 
patch and change gcc / glibc - use a custom kernel, modify configs, 
remove and add packages to the distro enough that they cant and do not 
have basic reproduceability that one would inherit into CentOS from 
Redhat[1].

Also, oracle lacks credible inhouse support. If you really want to get a 
contract, go with RHEL. or with CentOS and your local vendor. imho the 
support you get from the local vendor and CentOS is way better than what 
Oracle are able to offer for a linux OS.

Oracle are also not open source friendly - their sources and updates are 
not publicly listed[2].

Also, dont buy into that 'oracle test a lot more' - they dont. Their 
packages are inherited from CentOS and they actually rely on the testing 
that we do with the packages.

- KB

[1] Oracle Linux on a specific machine was only able to hit 12k emails 
per minute, whereas on CentOS and RHEL we got 18000 emails per minute. 
Same machine, same kickstart configs and the same package manifests + 
configs.

[2] If someone knows where they are - can you please tell me ?
