Description of problem:

'dnf update systemd' results in a coredump of systemd and sometimes other processes; this is new behavior since systemd-248.

The problem doesn't happen with 'dnf offline-(upgrade/distrosync)' or GNOME Shell pkoffline updates; and sounds like openqa tests don't hit this possibly because they aren't doing a user login before running the update.


Version-Release number of selected component (if applicable):
systemd-248~rc2  both -1 and -3

How reproducible:
5 for 5

Steps to Reproduce:
1. Workstation, login graphically
2. Launch GNOME Terminal
3. sudo dnf update *rpm

Actual results:

[18694.838020] systemd[1]: Caught <ABRT>, dumped core as pid 8919.


Expected results:

Not crash. Given that this is an ill advised update while logged in, maybe it shouldn't restart? I'm not sure if it's possible to just update it and not restart/reload, leave that up to reboot.

Looks like it's missing ACL?
