+### Putting it all together
+
+This following a script utilizing FreeBSD, jails and ZFS to automate
+provisioning a clean copy of a mysql staging database from a live replication
+slave.
+
+```bash
+#!/bin/sh
+
+echo "==== Stopping the staging database server ===="
+jail -r staging
+
+echo "==== Cleaning up existing staging server and snapshot ===="
+zfs destroy -r zroot/jails/staging
+zfs destroy zroot/jails/slave@staging
+
+echo "==== Quiescing the slave database ===="
+echo "FLUSH TABLES WITH READ LOCK;" | /usr/local/bin/mysql -u root -pmyrootpassword -h slave
+
+echo "==== Snapshotting the slave db filesystem as zroot/jails/slave@staging ===="
+zfs snapshot zroot/jails/slave@staging
+
+echo "==== Starting the slave database server ===="
+jail -c slave
