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.

It's one of the reasons I use Ubuntu LTS, the ZFS module is bundled by default.
Oh? Elaborate pls.
You can boot straight into snapshot, may be useful if an update went wrong or you don't like new kde.
You can change drives and raid configuration online. For example I bought a laptop that had windows preinstalled, so I used the second half of the disk space for linux, then I figured I don't need windows so I formatted windows partition to btrfs, added it as a new device, moved all the data there, deleted the old linux partition and extended the new one to the whole drive, all that easy and without reboot.
Oh nice. I think that all of those are possible with ZFS too. Although I'm pretty sure that the snapshot-boot is done outside of ZFS itself. As in, there's something else that takes the snapshots and makes them available to the bootloader. I think zsys used to do that in the experimental ZFS-on-root support that shipped in Ubuntu 20.04. I recall having a snapshot appear before every update and those snapshots were selectable from GRUB.
