Okay. I spent a entire day on it.

Basically, the link between /dev/raw1394 and /dev/null is not permanent. You can bash into your VM, call ln /dev/null /dev/raw1394, but it will last only until you re-start your container.

What I had to do, that seemed to be the simplest, but not the perfect approach, is to place the linking during the startup of the Container.

I thought in Running it as a service, but seemed too much for a simple job.

The way I finally came to work, (it's not pretty, but works), is by changing the CMD of the Dockerfile:

CMD sh -c 'ln -s /dev/null /dev/raw1394';
