This approach can be used as a way of mass production and can be easily scripted. The benefit of using snapshot is that you don't have to detach your zfs pool or have some way to block its writes before copying (with dd or recoverdisk, you _should_ do it to prevent accidentally making an inconsistent image) and since you have a new pool, you don't need to do reguid which is normally needed if dd/recoverdisk is used.
