Customer Demand and Open Source Development
• SUSE follows the “upstream first” principle
• Upstream first exceptions are only considered after analysis of risk, benefit, customer, and market demand
Swap over NFS – support customers on implementing clusters with huge memory demands and match features of typical UNIX systems. Implemented in SUSE Linux Enterprise 11 SP1, meanwhile accepted upstream, with SUSE's help.
Example:

SUSE® Linux Enterprise Live Patching
Technology “kGraft”
What?• Kernel Live Patching• Designed and developed by SUSE Labs• Ease of use: Builds on well known update processes
Status?• Currently integrated “Upstream” (=Kernel community)
Competitive Advantage?• Works with zero execution interruption
‒ As opposed to competition who stop the whole system (miliseconds to seconds range) when patching

SUSE® Linux Enterprise Live Patching
Kernel Live Patching – Use Cases
• Mission Critical systems‒ Improve general availability‒ Run until the next “maintenance window”
• Help with deployment challenges‒ No need to update all 10000+ systems at one shot, but be able
to run until a specific state is reached• See also:

Caveat: Not all issues can be fixed using “kGraft”;in special cases a reboot might be necessary
