Sure. I should improve this in the readme.
What runs as root are these three things only:
1. A little service that is part of my project, written in babashka, called
els-cloner
2. The criu binary
3. the criu-ns python script
That's all. CRIU currently cannot be run as non-root. The other two things
wrap CRIU and so also need to run as root... except I think I could make
the els-cloner service run as an els-cloner user and give it permission
only to invoke criu & criu-ns as root, and I should do that.
