Yes indeed, no parent/child between different snapshots

Maybe,do we need to have datetime of the snapshot to know the order of the snapshots.

I need to test the rollback of qcow2 and rbd, I don't know why more recent snapshots are not deleted if we rollback to older snapshots.

So there is no parent/child relationship between snapshots which we need 
to consider for qcow2, rados and sheepdog? 

But I guess we still want to track child/parent relationship inside the config file? 

I have no real idea for LVM - we need to test that.
