Installing UEFI ZFS Root on Ubuntu 19.10

▤ Summary

With 19.10 ZFS is available in main repository so we don’t need to add as in the previous Ubuntu versions. General idea of my disk setup is to maximize amount of space available for pool with the minimum of supporting partitions. If you are planning to have multiple kernels, increasing boot partition size might be a good idea. Due to Ubuntu 19.10 having some kernel version kerfuffle, we need to manually create initramfs image. The only remaining task before restart is to assign extra groups to user and make sure its home has correct owner.
