As per a recent update, the problem solvers at SUSE have designed and developed a technology, kGraft to deliver live, run-time patching of the Linux kernel, making it easier for IT staff to install critical security and other patches without system downtime. This open source solution is currently in the functional prototype stage and is planned to be submitted upstream to the Linux kernel within the next two months.
Although there are a couple of technologies that currently provide live patching of Linux, neither are available in the upstream Linux kernel.
According to Vojtech Pavlik of SUSE Labs, enterprise Linux users are eagerly awaiting an offering of this type which will enhance uptime in mission-critical environments.
