So it still doesn't take advantage of ZFS encryption, does it? That would be kind of neat if you could have a ZFS-encrypted drive without the extra layer of LUKS. And ideally the installer should let you select which datasets you wish to apply the encryption on.

Trying Out Ubuntu 20.04 With ZFS + Zsys Automated APT Snapshots

Does anyone know if it's easy to set up a Time Machine-like backup (automatic, incremental, filesystem backup) to FreeNAS like on macOS? I usually just need to turn on my MacBook Air when I'm home and it automatically takes a Time Machine backup which is sooo nice! I would like to do the same on my ThinkPad if possible

and has the added benefit you don't need the snapshot to exist in the first place to roll to it.
So far the only filesystems that support reflink are xfs, btrfs and ZFS.

i just dont think filesystem snapshot are the correct way to deal with package upgrades.
there are too many folders who need its own partition in this case (eg srv home)
ZFS doesn't use partitions per say. It's "datasets" are separate from the OS's view but use the same storage pool and don't have a fixed size. Pretty much obsoletes partitions. In theory you could have Ubuntu, Gentoo, FreeBSD and ?macOS hack all installed to the same disk all booting from ZFS without any partitioning and no wasted space just select the OS/root combo from the boot loader and go. Example of someone that did this.

and if you change their contents and roll back afterwards your changes have gone away. thats not way i expect from a snapshot made by a package manager
on ZFS you can do the same

I tried this out, it's nice.
Here is how you use it:
Step 1 - Install Ubuntu on ZFS in the installer.
That's it, there is no step 2. When you update you just have them and can roll back in Grub should you ever need to. A user would never even need to know.
