All of the scripts are designed to work with mount points. Every bit of data that is necessary for a reinstall is included in each apps README file. This means that jails can be destroyed and rebuilt without losing data.
If you do not want to use mount points, the script will install the apps and its data inside the jail and everything will work normally. But be warned, when you destroy the jail, the data inside it will be lost.
Mount points make it easy to destroy and recreate jails without losing data. Each application has a list of mount points that must be mounted if you choose to store all the data outside the jail. These scripts have all been tested by doing an initial install, then a reinstall. If the data is mounted into the jail on a reinstall, the script will skip certain steps to prevent data from being overwritten.
Some of the scripts have variables that should be set before running. These could include passwords, server values, and database names. Most will be set randomly, but some require user intervention. Each applications README file will let you know what to do.
Variables that should be changed are listed on the README file of each app. Any variables that are not listed, should not be changed unless there is a really good reason to do so.
Some applications require certain jail properties to be activated. You will have to do so with whichever jail manager you are using. They all have a way to set jail properties.
