good point. I should mention mdadm vs btrfs vs zfs options at the begining of the procedure.
Unfortunately, I do not know the answer as I have not tried using two thin partitions.
What would the advantage of making two thin pools be as opposed to having just one thin pool?
(and what does having a thin pool with just one volume (the root volume) in it accomplish beyond making it just a static (non-thin) root partition?)
Separate pools are to still have bootable dom0 even if you run out of space in the vm-pool. And root-pool being a thin pool is to allow thin snapshots there (something that wyng-backup and similar tools can utilize).
This is what installer does by default nowadays if you select LVM (default) partitioning.
