Ubuntu 19.04 Makes It Easier to Manage Reboot-free Kernel Updates - Windows Users Can Eat Their Hearts Out
Users of Canonical’s Livepatch service — which lets you install Linux kernel updates without rebooting — will find additional settings available in Ubuntu 19.04.
The feature, which made its desktop debut in Ubuntu 18.04 LTS, is free for Ubuntu desktop users on up to three separate machines.
The Ubuntu Welcome screen includes live patch set-up as part of its fresh-install orientation but is easily skipped.
With all Linux distros you continue working/playing during downloads and updates, and some kernel level updates are applied when you do a quick reboot later on (around one minute or less is all it takes). I've always loved this about Linux as I recall sitting for ages whilst MS Windows used to apply its updates and reboot three or four times. Ubuntu, RHEL and Suse Linux have been debuting their live kernel patching but was usually being seen on enterprise installs, but now it seems this is going consumer level too. You want stability and minimum downtime? You want Linux..
