zsys

This is a good thing for ZFS and public perception of ZFS. Ubuntu has made some very poor choices with how they've integrated ZFS - * zsys has both implementation and design flaws. They utilize two zpools - one with limited feature flags that GRUB can use and one general pool, and then try to tightly couple datasets between those two pools while coordinating snapshots. zsys routinely runs a system out of space due to not cleaning up snapshots. It's been known to destroy user data as well. https://github.com/ubuntu/zsys/issues/196 https://github.com/ubuntu/zsys/issues/218 * Their packaging was and is still very sloppy. It's quite common to catch people running one version of kernel modules and another version of userland tools - often multiple releases apart. This has led to some serious problems.

Ubuntu isn't my preferred OS these days, but I've had excellent experiences with it's ZFS root installs as well as it's included zsys: https://github.com/ubuntu/zsys

This is implemented for Arch Linux with bieaz or zbm; and Ubuntu with zsys. bieaz: https://openzfs.github.io/openzfs-docs/Getting%20Started/Arc... zbm: https://github.com/zbm-dev/zfsbootmenu zsys: https://github.com/ubuntu/zsys

Looks to be that's what they have done. They've developed a new tool called `zsys` https://github.com/ubuntu/zsys which will help with system administration, rollbacks, auto snapshots before and after package changes. I believe it will also support boot environments.
