### 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
echo "==== Cloning the slave snapshot to the staging server ===="
zfs clone zroot/jails/slave@staging zroot/jails/staging
echo "==== Installing the staging mysql config ===="
mv /jails/staging/usr/local/etc/my.cnf /jails/staging/usr/local/etc/my.cnf.slave
cp /jails/staging/usr/local/etc/my.cnf.staging /jails/staging/usr/local/etc/my.cnf
echo "==== Setting up the staging rc.conf file ===="
mv /jails/staging/etc/rc.conf.local /jails/staging/etc/rc.conf.slave
mv /jails/staging/etc/rc.conf.staging /jails/staging/etc/rc.conf.local
echo "==== Starting the staging db server ===="
jail -c staging
echo "==== Make sthe staging database not pull from the master ===="
echo "STOP SLAVE;" | /usr/local/bin/mysql -u root -pmyrootpassword -h staging
echo "RESET SLAVE;" | /usr/local/bin/mysql -u root -pmyrootpassword -h staging
