    Default 3 new systemd users??

    In the last couple of weeks in my tumbleweed partition the system has added 3 new users - all systemd-<something>. Their login is disallowed but it's still preventing me from having autologin. I cancelled them all at first but they came back.
    Is this something new for tumbleweed or is there something more sinister going on? (I'm not particularly bothered by the inability to autologin).

    It happened to me this time ago

    And I still have systemd-coredump and systemd-timesync as users in Yast> users and groups.
    Occasionally they eliminate them, but they reappear

    If you use sddm have you by any chance changed the MinimumUid (/etc/sddm.conf) from it's default of 1000

    Question Re: 3 new systemd users??

    1. Code is fact; documentation is fiction.

    Without inspecting the code, it is actually quite difficult to establish a relationship between the latest "systemd" user scheme (deep in the system) and, a GUI's Display Manager (SDDM, GDM, whatever) [located at the very top of the system's scheme of things and, isolated from the deeper "system" things -- either X11 or Wayland is between the Display Manager and things such as "systemd" (which is managing system things close to the kernel) ].

    Please indicate which Desktop GUI you're using -- KDE? GNOME? Something else?
