Ksplice: Deeply Integrate In RHEL 7 And Beyond
For RHEL 7 deeply integrate Ksplice in every part of the OS to further advance the OS into the next level of server management.
This is already available for Fedora (http://www.ksplice.com/).
However, deep integration has huge advantages in the cloud.

My understanding is that Oracle bought ksplice, and Oracle deems RHEL and CentOS as "Legacy Ksplice Uptrack customer supported kernels". Support for this would likely need to originate from Oracle, who is a direct competitor to RHEL in the EL space.
From their acquisition note:
"PRODUCT SUPPORT
The combination of Ksplice technology and Oracle Linux Premier
Support is expected to be the only enterprise Linux provider that
can offer zero downtime updates, and Oracle plans to make the
Ksplice technology a standard feature of Oracle Linux Premier
Support."
I'm surprised RH didn't try to beat Oracle to ksplice ages ago, it provides a large competitve advantage over other enterprise server OS's. The code is/was open source, I'd have thought RH should sponsor a fork to bring it back to the community and ship with RHEL7.
The business problem I'd be trying to solve would be less downtime when applying essential security updates. Even in a cluster enviroment (especially with things like NFS services) the failover time causes some disruption. And not everything is clustered, it would massively benefit smaller non-clustered deployments.
This seems an obvious thing to want!
I am rather suprised to see this as a dead thread. I know that I personally would love to see kernel patching no longer require a system reboot. I know that Oracle bought KSplice (with the rest of the world), but as this is not really a new functionality request, more like a request for basic functionality to become standard, I expected this thread to be a cornocopia of posts, discussions, agreements and/or arguments.
Anyone else sick of the constant monthly reboots every time a kernel patch comes out? In the industry I am in, it is required for us to reboot ASAP following a kernel patch to meet security guidelines. Are systems are scanned weekly and I have 30 days to meet any security concerns (such as having 2 kernel versions available, since the old one may be exploitable).
There is always the kernelcare.com one as well as an alternative. I would love to see redhat buy them and opensource it for the good of the community. I know however that redhat is very active.
