Comment # 37 on bug 1169783 from Robert Kaiser

That said, switching all those paths to /var/run did not fix it for me, but
then, I also do not run into the timeout any more that ended up giving me the
possibility to work around the issue, so my system doesn't boot at all any more
atm and I have to use the rescue system from a Leap 15.1 DVD to get to
anything.
This new problem happened after upgrading from Tumbleweed 20200416 to 20200422,
and looking through the emails on packages updates in between those I see
systemd 245, pointing to
https://github.com/openSUSE/systemd/blob/SUSE/v245/NEWS whioch mentions an
"UPGRADE ISSUE" connected to plymouth which lead me to
https://bugzilla.redhat.com/show_bug.cgi?id=1807771 and
https://gitlab.freedesktop.org/plymouth/plymouth/-/merge_requests/99 - which
could also be connected.

Now applying that on the system before rebooting does not fix this for me yet,
though I see the prompt for a very short time on the console output screen. I
did reboot and try to enter the password when that was visible, but not not
complete that (3-4 stars appeared there), but then when the switch to the
three-dot-text screen of plymouth comes up, now it actually switches to the
text-screen plymouth prompt and that works correctly...

So not completely fixed but getting closer...
