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.

I have no idea when I last updated my RasPi 0s (none of which is exposed to the public).

Most images and distros are just Raspbian at their core and as such are pretty easy to upgrade.

I upgraded my homebridge/pihole from Bullseye to Bookworm just a few days ago and it went off without a hitch.

Did the same with raspi3... It broke too many things for me and couldn't be restarted. I then completely reinstalled it.

Aww that sucks. To be fair I did take a full image backup before attempting the upgrade in case something went awry.

I also had a complete backup, but I was also considering reinstalling it at the time anyway. Accordingly, only partially restored data. But you should definitely make a backup, that's true.
