How to live patch Ubuntu Linux Kernel without rebooting the server Ubuntu Linux version 16.04 LTS supports live patching for both enterprise and the Ubuntu community members. The Canonical Livepatch Service is an authenticated, encrypted, signed stream of live patch kernel modules for Ubuntu servers, virtual machines and desktops. Please note that this service is free up to 3 servers running 64-bit Intel/AMD Ubuntu 16.04 LTS. Think of mission critical systems in stock exchanges, hospitals, etc. You can't have such system rebooting during critical times, and you also cannot afford 3 to 4 hours downtime while a farm of servers are all busy rebooting. It amazes me still that many corporates choose to pay for Windows server OS and then submit themselves to hours of downtime while reboots take place, and I have seen that their systems are certified to run on Linux servers. Why on earth would they then not run them on Linux servers? Has IT today become so narrowly focussed that they can only support one OS? I daily work between Windows, Mac, Android and Linux - its really not difficult. If your IT is so ill equipped, replace them with better people that want to learn!
