Using the jail Module with (Base-)Lua on FreeBSD

Dear FreeBSD Community,

I am currently working on a FreeBSD system where I am managing multiple 
Jails using Bastille. Here's a snapshot of the active Jails for context:

```
user@microserver:~ $ jls
    JID  IP Address      Hostname                      Path
      1  10.0.0.1        dns /usr/local/bastille/jails/dns/root
      2  10.0.0.10       redmine /usr/local/bastille/jails/redmine/root
      ... (truncated for brevity) ...
     63  10.0.0.18       webproxy /usr/local/bastille/jails/webproxy/root
```

I attempted to use the jail module with Lua (via /usr/libexec/flua), but 
I encountered issues when trying to load or interact with it. Below are 
the steps and results:

```
user@microserver:~ $ /usr/libexec/flua
Lua 5.4.6  Copyright (C) 1994-2023 Lua.org, PUC-Rio
> package.cpath
/usr/lib/flua/?.so;/usr/lib/flua/loadall.so;./?.so
> local jail = require("jail")
> print(jail)
nil
> jail.list()
stdin:1: attempt to index a nil value (global 'jail')
stack traceback:
         stdin:1: in main chunk
         [C]: in ?
> local path = package.searchpath("jail", package.path)
> print(path)
nil
> local path = package.searchpath("jail", package.cpath)
> print(path)
nil
```

It seems that the jail module is not accessible through Lua’s require() 
function, and package.searchpath doesn't locate it either in 
package.path or package.cpath.

Questions:

- Is the jail module supposed to be available by default in 
/usr/libexec/flua?
- If not, what are the steps to install or enable it?
- Are there any specific dependencies or configurations needed for Lua 
to interact with the jail subsystem on FreeBSD?

I’d appreciate any guidance, as I am trying to leverage Lua scripting 
for automating jail management tasks.

Thank you in advance for your time and help!

Best regards
Matthias
