I use Ubuntu 14.04 (LTS) on the server and various kernel updates come out quite often, but I don’t want to restart the “combat” server every time.
What are the methods for updating the kernel without a complete reboot of the server?
I know about ksplice , kexec , but which one is the most reliable?

kexec is the launch of a new kernel, almost a reboot, only without going into bios.
