That's not a sensible setup, by the way.  Only a single partition is
needed to form a ZFS 'pool', and then ZFS allocates its own 'logical
volumes' (usr, home, var...) out of that.

So, ZFS more or less replaces LVM functionality.  Maybe there ought to
be a 'Guided partitioning using ZFS' option...

That's not to say it absolutely cannot work.  I'm not sure.  There could
be a valid use case if someone merely wants to try ZFS and dual-boot it,
if their entire disk is already LVM.  What does work well is using LVM
logical volumes as virtual hard disks for a Xen or KVM guest for example.
