Active nodes exist as a linked clone of the base image. I ran into the need to make some persistent changes to a base image. I did not want to set up another machine just to adjust my images so I figured out how to use my Eve-NG machine to do it. Read on to find out how. Continue reading →

I wanted to incorporate setting up UNetLab in another article but decided to award the setup process with its own post.
