Live Patching Lands in SUSE Enterprise Linux 12
Page 1 of 1
The new SUSE Linux Enterprise Live Patching technology is derived from the open-source kGraft project, that SUSE has been leading in the upstream Linux community. The kGraft project is about enabling patching of a live running kernel without the need to shutdown and entire system.
There are multiple efforts in the Linux ecosystem for live kernel patching that compete with what SUSE is doing. Red Hat has a technology called kpatch that enables live kernel patching. The first vendor to fully embrace and develop live kernel patching was KSplice, which is now owned by Oracle.
