    Default SUSE Develops New Way Of Live-Patching The Kernel

    Phoronix: SUSE Develops New Way Of Live-Patching The Kernel

    SUSE has announced they have developed a new way of live-patching a running kernel to avoid having to reboot the system when upgrading to the latest kernel version. There's been Ksplice as the leading means of live-upgrading a kernel but SUSE hopes their kGraft solution will be the superior mainline solution...

    Kexec boots a new kernel on the old, but you still need to run init shutdown and then boot the system again, you are only skipping the initialize process of BIOS/UEFI. Live-Patching means patching the kernel without stooping any user processes and reinit the system.
