Hi,
Akemi is correct, the EUS packages are not released to the public
(except by accident occasionally). The also applied to kernels that are
released for EUS.
The kernels that we get and release for all the SL6 releases (6.0 ...
6.n) are the kernels that we get from RedHat's public ftp site, that
they release for their general RHEL6 release.
These kernels work fine on the SL 6.0 release, and we test these kernels
on a SL 6.0 test machine. If there are occasions that a related
packages are needed to be upgraded for a kernel upgrade we add or update
the appropriate package. Thus far we haven't had to do that for SL6,
but we commonly had to do that for SL4.
In summary, SL 6.0 will get the same security update kernel that SL 6.5
gets, when the time comes. We are able to do that because RedHat has
promised that they will not remove and/or significantly change API's,
libraries, etc.. in their kernel. That is why it is still a 2.6.32 kernel.
They have kept that promise for RHEL3, RHEL4, and RHEL5. We expect them
to continue doing it for RHEL6 as well.
To answer your question in short. Yes, it is safe to install a
2.6.32-131x kernel on a SL 6.0 host.
