These features are  not suitable for production use. However, these features are included  to provide the feature with wider exposure.

Unbreakable Linux Support

Enterprise Linux offers an option to keep your operating system up to date with latest operating system patches using up2date.  To be able to  use this option you need to have Unbreakable Linux  Support. For more information  please visit http://linux.oracle.com

Note: Prior to using up2date, import the RPM-GPG-KEY for Enterprise Linux:

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY

Known Issue

If updating from OEL 5 GA or RHEL 5 GA using up2date, you may encounter the following error:

Unresolvable chain of dependencies:
xen-3.0.3-64.el5 requires xen-hypervisor-abi = 3.1

This happens because a kernel-xen package update is needed by the xen package, but 'kernel*' is part of the up2date pkgSkipList. To get
around this, add 'xen;xen-devel;' to the the pkgSkipList line in /etc/sysconfig/rhn/up2date and then run up2date. You can update the xen and kernel-xen packages together later via 'up2date --force xen kernel-xen'.
