As the zones use ZFS as root filesystem it's easy to do a zfs
snapshot/clone to reproduce a zone. The different zones have only

to read from global's /etc/hosts the ip address. Zonerootpath is
/zones/zonename and /etc/nodename must contain as well. The
name of the zone is always identical to the hostname of the zone.
That rule is not from OpenSolaris but from me. ;-)

is not for general use...
#!/bin/bash
echo "Creating zone $1 from zone TEMPLATE"

zoneadm list -cv | grep $1 && exit -1
echo -n "Retrieving TEMPLATE's IP: "
TEMPLATE_IP=$(grep TEMPLATE /etc/hosts | nawk '{print $1}')
