Thanks for the explanation. But what if I don't want to zero everything? I
only want to return everything back to the state it was before I created the
snapshot.
So you're not worried about the security implication of leftovers in free
space, and just want a base image to clone for new customers?
Yes I am. This is exactly what I'm worried about. I just need to know how to zero out any "left over" bits of data that would be left over after removing a snapshot. I use snapshots for backing up a volume (by running rsync against the snapshot to a remote server)
