Comment # 1 on bug 1070756 from Gerald Pfeifer

Still the case, as seen from the following zypper dup output:

164/358) Installing: sane-backends-1.0.27-3.3.x86_64 .......[done]
Additional rpm output:
warning: /etc/sane.d/dll.conf created as /etc/sane.d/dll.conf.rpmnew
Failed to try-restart saned.socket: Unit saned.socket is not loaded properly:
Is a directory.
See system logs and 'systemctl status saned.socket' for details.
