I've heard that you should be using the appropriate stage3 archive for the profile you want to use, but what exactly are the differences between them? I'm asking this because I want to try doing a Hardened/SELinux/Musl/LLVM install, and there's a profile for that, but not the stage3 archive. I was thinking of starting with either Hardened/Musl or LLVM/Musl. Any thoughts on that?
