Bernhard now could this things to be made default automatically for all users? or at least some of it - 26GB in `/tmp` for a user that has no clue about file system layout would be a rather hard thing to understand - I coudl find it with `du -hsc /tmp/*` and handle it by just `sudo rm -rf /tmp/kde-<user>/dolphin*` but what about users that do not have that internal knowledge of Linux?
