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.
