Rather than using sux or some other method to run the entire Emacs as
another user like root, try Tramp mode:

C-x C-f /sudo::/etc/whatever-you-want

That way, your Emacs session runs as you, and only the bare minimum
needed for root permissions is using sudo.  (You can also do
"/su::/etc/whatever" if you're on a machine with a real root account.)
