> You can realistically read the entire source code of OpenBSD, compile it, and know exactly what's on your computer front to back. To do the same with Linux is a research project.

openbsd/src is over 17,000 *.c files with over 3 million lines of code

That's just a light weekends reading for your average testicle in an eggcup.

I don't mean just FreeBSD, being quite a bit smaller than Linux is still a gigantic, 30 year old, codebase. You can not realistically read through the entire openbsd codebase unless you spend a decade at it

That's assuming you read all that firmware code already...
