Re: New tool to reduce emacs start-up time on Linux

[Blake Miller]

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.

I see, I dont understand all the terminology here, which explains my
confusion. As long as neither the emacs daemon or client run as Root,
then that would take away my concern. Could you also elaborate on what
it is that runs as Root?
