too bad, no luck here the second time with ext4. i had slight variation, about adding the update/update-non-oss repos as well. will try some more (but enough for today) and do the exact steps i documented in my lengthy comment. I think it should reappear then. maybe its even some race condition? or timing issue with the installation of packages and all. the journal shows quite a number of events in or around that systemd package incoming/deleting/updating, as if there were some parallel tasks and multiple things going on at once, multiple rpm packages becoming installed and still being executed and arriving in the log... at least thats the impression to me here. so maybe it could be some interaction and runtime problem about cpu speeds, disk activity, fragmentation, delays, race conditions or whatever such stuff? could this be possible? or is a zypper dup (and the internal things happening inside it, such as rpm updating the packages and scripts...) all sequential? doesnt look like everything were purely sequential to me if I am not mistaken.....
