Is your feature request related to a problem? Please describe.
We are currently using a very old and custom version of CORE (v4.8) for our university lab courses. The main change is an OverlayFS feature. We use OverlayFS to give each node its own overlay path and then its own filesystem. This is used in some of the exercises so that we can send files from one node to another. Now we are integrating OverlayFS into a newer release of CORE. We would like to know if there is any interest in this feature becoming a part of the main CORE project.

Describe the solution you'd like
Add the ability to configure an OverlayFS path to a created node so that during runtime different nodes can have different filesystem contents.

Describe alternatives you've considered
Maintain a separate version of CORE with OverlayFS.

Additional context
The development of the newer version was started some time ago with CORE release 9.0.3 and has not been updated since. If there is interest in this feature we can work on integrating our changes on the latest commit and submit a merge request.
