Title: Add support for Ksplice

openSUSE-11.2: Rejected by Andreas Jaeger (a_jaeger)
reject date: 2009-08-12 10:52:21
reject reason: Let's evaluate for 11.3.
Requester: Important

- openSUSE-11.3: Evaluation
+ openSUSE-11.3: Rejected by (jbenc)
+ reject date: 2010-03-24 12:07:28
+ reject reason: Not enough resources in the kernel teams to provide
+ updates as ksplice patches.
Requester: Important

Requested by: Stephan Kleine (bitshuffler)

KSplice allows it currently to apply most but not all kernel updates
without the need to reboot which is especially great for servers. It's
backed by a newly founded corporation that continually tries to improve
it so hopefully sometime in the future a reboot wont be necessary for
any kernel update.
Fedora as well as Ubuntu already support it so openSUSE shouldn't stay

Ksplice will be THE reason for many webserver admins to choose Ubuntu
and not openSUSE. Don't lose any ground on the server market, make use
of Ksplice too.

#2: (bmwiedemann) (2009-10-09 11:37:37)
A presentation at LinuxTag 2009 from the ksplice guys as well as says, that all security patches
can be made rebootless. Only 12% of 64 studied patches needed manual
extra code (e.g. for updating structure data).
The proper way of distribution would of course also update /lib/modules
and /boot/vmlinuz/initrd but possibly patch the running kernel via a
rpm post-inst script.
I have noted that in the past, openSUSE kernel-updates happened later
than those for Debian and Ubuntu, but often contained several fixes at
a time. I guess, part of this is due to the reboot needed after a
kernel-update, so with Ksplice critical security fixes could reach
users faster.

#3: John Sheehy (jesheehy) (2010-02-10 03:36:17)
Ksplice or similar functionality is critical for production servers,
especially those exposed in the DMZ.
In the future there should never be an excuse that a security patch
didn't get applied since it required a reboot and a maintenance window
wasn't available right away.

+ #4: Jiri Benc (jbenc) (2010-03-24 12:06:24)
+ This is really two requests:
+ 1. Add the ksplice kernel module into the distribution.
+ 2. Provide the kernel updates as ksplice patches (most likely as an
+ alternative to the normal updates).
+ While 1. is easy, I don't see the kernel teams having enough resources
+ for 2. It will require the community to step in; anybody who's
+ interested in doing the work is welcome.
+ That said, 1. does not make sense without 2. If we find somebody who
+ does the work (please speak up if you are interested!), the module can
+ be distributed as a KMP and/or this feature can be reopened.
