ubuntu-zfs

Ansible playbook that implements https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS

Usage

• Edit ansible/vars.yml with your desired settings.
• Run packer build -on-error=ask ubuntu-zfs-{{ mbr || efi }}.json to test the playbook in a Virtualbox machine.
• The last provisioner is simply a shell provisioner that runs false, so you can examine the resulting system once the playbook has completed.
• Playbook hasn't yet been tested on real hardware, will report back with more commits
  • it should go without saying, but trying to run this on real hardware will result in data loss
