One of the new features that Ubuntu 19.10 Eoan Ermine introduced was support for ZFS as root. It was an initial and experimental support that improved a lot, partly because it was complete, in Ubuntu 20.04 LTS Focal Fossa, but it seems that things can still be better and Canonical has already got to work. Its developers will make further improvements to Ubuntu 20.10 Groovy Gorilla, the version that will be released in October this year.
Ubuntu 20.10 will be the first release after a new LTS version. Until the next version supported for 5 years, 3 in most official flavors, it will still be two years and three versions (20.10, 21.04, 21.10), but it seems that Canonical wants to make sure that the ZFS it works perfectly in what would be an important function for Ubuntu 22.04 IAnimal IA target. And it is that, in the past, until Linus Torvalds advised against its use in Linux.
Ubuntu 20.10 will arrive in October with an improved ZFS
Although they have included full support in Ubuntu 20.04, the ZFS as root continues to be offered as something experimental, and there are users who claim to have lost data due to the use of this file system that Torvalds advises against using, at least at present. And it's a shame because, if it worked well, we could use the checkpoints without having to rely on third-party software or a separate disk, among other things.
Canonical developers will keep ZFS as root in their sights for Groovy Gorilla and several of them are already holding talks. Jean Baptiste Lallement, from Canonical, assures that has started to analyze the encryption ZFS and has held several meetings on the topic "ZFS and Enterprise Desktop"
Ubuntu 20.10 Groovy Gorilla will be a normal cycle version supported for 9 months whose official launch is scheduled for October 22, 2020. Its Daily Builds are now available in the Canonical FTP server.
