Ubuntu can upgrade the kernel at will.

Canonical announced the release of "Livepatch Services". After installing updates for Linux Kernel, you do not need to restart the computer. You can update the kernel package without restarting the Linux 4.0 branch. However, Ubuntu is the first release that provides this function.

Tom Callway from Canonical said: "We are very pleased to announce the launch of the new Ubuntu service-Canonical Livepatch Services, which can be used by any user in the current installation version. This new Real-Time Kernel Patching service can be applied to any Ubuntu 16.04 LTS System (using the Linux Kernel 4.4 Kernel) to minimize unexpected downtime and maintain the highest level of security ."

Each user can deploy Canonical Livepatch Services on up to three devices. If you want to continue using this service, you need to purchase the Ubuntu Advantage support package. For ordinary users, this service is not very practical, but it is very significant improvement for the server side.
