Yes. I just came up with it but it makes sense (I think). For /etc/sudoers use: sudo LOGNAME=USER EDITOR='/usr/bin/emacs' visudo Note that -u USER is isn't necessary with LOGNAME. Tildes (~) in config files have to be replaced with (user-login-name), e.g.: (setq load-path (append load-path `(,(format "/home/%s/.emacs.d/emacs-init/" (user-login-name)) ,(format "/home/%s/.emacs.d/emacs-init/w3m/" (user-login-name)) ,(format "/home/%s/.emacs.d/emacs-init/gnus/" (user-login-name)) ))) `user-login-name' will report the (correct) user even without the LOGNAME set (however not in sudo invocation, which is why LOGNAME *is* set there) so it will work transparently, is the thought. -- underground experts united http://user.it.uu.se/~embe8573
