Comment # 11 on bug 1020327 from Fabian Vogt

Some more information:

I did not see the plymouth crashes as I also updated to a version of plymouth
in Base:System, which is so new that it contains the bugfix for that crash, but
too old so it does not work _at all_ (drm driver not loaded...).
Plymouth git works fine.

The root cause is that systemd-vconsole-setup touches the same consoles more
than once. This is definitely not how it should behave. Instead:

* During initrd, only configure all present consoles (tty1 usually)
* After this is done, run plymouth
* More consoles appear, udev calls systemd-vconsole-setup through rules
