Bind and start the original domain.
Execute the sys-unconfig command.
After the sys-unconfig command completes, the domain halts.
Stop and unbind the domain; do not reboot it.
Take a snapshot of the domain boot disk image.
primary# zfs snapshot ldmpool/ldg1/disk0@unconfigured
At this point you have the snapshot of the boot disk image of an unconfigured system.
Clone this image to create a new domain which, when first booted, asks for the configuration of the system.
