Hold on, I think I may not be understanding something. If "sudo -e
/etc/hosts" will still work, why won't "sudo emacs /etc/hosts" ?
Andrew.
"sudo -e" creates a temporary file owned by you containing the file contents,
then has your editor access it; when your editor exits, the temporary file's
contents replace the original file.
"sudo emacs" runs emacs as a new user; AIUI, in the current Wayland security
model, emacs running as another user cannot access the Wayland server, because
it's not the same user.
