From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Apt will install a package but if a service is in use the kernel still runs the old until you stop the services and restart. its just not apparent to the user. This is not live patching, live patching is when kernel will load a new patch and you temporarily have two states and during a momentary blip pass all control to new kernel...this is typically for mission critical server that can't have downtime. Just running a regular update does not do this.

Interesting! But afaik apt also has mechanisms to only restart necessary services.
Not sure how to check on apt, but zypper uses ps -s arguments and shows you all the running processes/services that need a restart before the system is fully using all updates
