Comment # 91 on bug 1169783 from Hans-Peter Jansen

I always use zypper.

Meanwhile, the problem was disclosed. Since some time and up to plymouth GIT
HEAD, plymouthd could crash, if DeviceTimeout is undefined (iow. 0). Defining 

[Daemon]
[...]
DeviceTimeout=5

solved it for *all* crashing systems. Upstream doesn't want to apply a simple
fix to prevent a DeviceTimeout=0 setting, hence we might want to deal with this
in %post or apply a local patch. Probably we just missed to install a properly
adjusted plymouthd.defaults. But I haven't fully grokked the plymouthd.conf and
plymouthd.defaults handling, yet, sorry.
