Ubuntu 24.04

From the comments: "These exact instructions are not working on Ubuntu 24.04. Ubuntu has changed the naming of ZFS partitions, partition 2 and 3 are switched around, and the boot/efi folder is now different."

I don't have my dual-disk test system any longer, and so can't adjust these steps myself.

Overview

Ubuntu Desktop 20.04 supports a single ZFS boot drive out of the box. I wanted a ZFS mirror, without going through an entirely manual setup of Ubuntu as described by OpenZFS in their instructions for Ubuntu 20.04 and instructions for Ubuntu 22.04

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1
