NO, NO, NO. There is still only *one* physical copy of the data
after creating a snapshot. You have simply created a "branch point"
which can now diverge as each branch is written to.
Then why was it suggested that I should zero my new customer LVs upon
creation? Please remember that my snapshots will not be written to
