There are a couple of open bugs[1][2] related to grub and ZFS that make it a little tricky to get ZFS on your root volume, but it is doable: https://github.com/zfsonlinux/pkg-zfs/wiki/HOWTO-install-Ubuntu-16.04-to-a-Native-ZFS-Root-Filesystem https://github.com/zfsonlinux/pkg-zfs/wiki/HOWTO-install-Ubu.... I expect those issues to be resolved before 16.04 is released. Even with those fixes, the interactive installer doesn't support ZFS yet so you will still need to drop to a shell to actually setup your zpool and your partitions.
