Wow! Indeed this change fixes the issue for me! Thanks a lot! About updating the ISO. Sure it would be appreciated. Unfortunately we've given out promotion DVDs, which we obviously cannot update. Also ISOs are meanwhile on media, which we do not control. Since this issue means complete data loss for the customer (I was happy that I've updated my system that early), I would like to know if you can think of any workaround, which the customer can apply in the emergency shell (or by other means). Then we could describe this below "Known issues for Leap 42.3". And now I'm wondering, whether we see this issue also on sle12-sp3. I haven't tested this yet.
