Looks good.

In #23 (closed) you mention that you'd like to document, that it is necessary to run the script as root. Not sure whether it is true, but maybe you should address it here. Anyways this is not a blocker, so feel free to merge it 👍

From my latest experience it does not need to be run as root. I edited the issue and described it better by using my latest findings. I also edited this MR and mentioned the issue. Hope it makes more sense as of now.

Ok. I see that you are not maintainer so I'm going to merge it 🙄
