While Unbutu supports ZFS on root filesystems with an easy snapshot and rollback mechanism called ZSYS, ZSYS is [soon going to be deprecated](https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1966773) and the installer does not offer an easy way to setup mirroring. In this guide, I will walk you through how to set up Ubuntu with root on ZFS, mirroring with both the root and EFI partitions, and remote unlocking + boot into a snapshot with ZFSBootMenu.
