Not if you save your initial copy a master file (zfs send ... >
master_snapshot) then populate it to a pool after detaching your first
pool (cat master_snapshot | zfs receive ...).  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.

Cheers,
