root disk formatted with ZFS

cn flag

I am trying to install Ubuntu Server 20.04 or 21.10 with ZFS on root disk. I can't find an option to use ZFS (just xfs and btrfs) in the installer.

Is there a way to boot from a ZFS formatted disk?

Since Eoan Ermine (Ubuntu 19.10), Ubuntu installer for desktop only can use ZFS as root file-system but is still experimental.

The current LTS, Focal Fossa (Ubuntu 20.04) provides only a mono-disk installation, I do not know the difference with a server installer, but this is the only Ubuntu way to install on a root ZFS.

However, OpenZfs provide a way to install Ubuntu on ZFS root:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
