Is there a manual page that describes all the directory paths that can be modified using wrapper arguments?

I know about the data and the projects directory properties, but are there more? I’m trying to install on a read-only filesystem.

```python
-Ddata.dir=data
-Dignition.projects.dir=/path/to/projects

```

That might be it for JVM args...

You don't need to set the projects dir separately if you are moving data, it's relative to the data dir.

There are more paths in `webapps/main/WEB-INF/web.xml` that might be changeable.

I don't know if you'll have any luck with a read-only filesystem.
