filesystem - Should the root folder (/root) be empty?

I have been moving files around to prepare for a remaster. I put some files into root, which I though might help an issue I was having with auto login in live mode.

anyway, putting files into root changed nothing, thing is I cant remember if root was empty or not when i started so, should the root folder be empty, and if not, what should be in there?

thanks

/root is simply the homedir for the root user.

By default, all that should be in there are some dotfiles, like .bashrc and .profile.
