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.

With tbis update system, I don't understand why you can't use your phone while doing it.
You can. Google pixel updates are just a reboot. Sadly many OEMs don't do A/B updates, like samsung, so your phone can't be used while updating the system partition
It's worth mentioning that they often do this to reduce flash size, i.e. save 💰. Virtual AB was introduced to help with this but it's relatively new. With it, there's no need to reserve the space for 2x system partition. The needed extra space during update is taken from /data and released post success. There's also a compressed virtual AB scheme now which helps reduce the space needed from /data to enable really space-crippled devices like CCwGTV and other Android TV things like Sony and other TVs.
Interesting! I didn't know that, thanks for responding
