If that is the case, then that is an argument for not backing backups in any
world (or group?) writeable place.  It's not specific to /tmp.

I often work in /tmp/ on files that I know I won't want to keep.  I still
find backup files useful, even for these temporary files.  Yes, I can use
C-x C-w instead, but that's something I have to remember to do each time,
*before* I start editing, otherwise it's too late.  I find it a lot more
convenient to have Emacs automatically make backup files, and think it would
be good to have a user-configurable option to do so.  Not that it matters to
me personally, I can put some magic Emacs Lisp in my .emacs to get the
effect I want.

Chris.
