plymouth:
 added 080-do-not-ignore-fb-if-drm-is-not-in-use.quilt 
  (backport of upstream changes)
 added 085-switch-to-welcome-and-snapshot-before-quit.quilt
  adds a ExecStartPre to the plymouth-quit service to call
  univention-welcome-screen to switch to the welcome screen and take a 
  snapshot to /tmp/.univention-welcome-screen.png

univention-bootsplash (univention-welcome-screen):
 new systemd service to start univention-welcome-screen to show the 
 welcome screen

univention-system-setup:
 startxwithfirefox start univention-welcome-screen after setup in a mode,
 where plymouth is restarted, a snapshot is taken and shown

Created attachment 8557 [details]
debug logfile

Runs very well on KVM, only one slight hickup when displaying the file from /tmp, i guess that is ok.

Unfortunately nothing is displayed in a Virtualbox VM. A quick debug produced the attached logfile

I've disabled the welcome-screen installation for the 4.2 RC:

r78016:
* Don't install univention-welcome-screen until Bug #43656 has been
  fixed

First, the welcome-screen is shown. After 10 seconds, a black screen is shown, if I press ESC the message: A start job is running for Wait for Plymouth Boot Screen to Quit (2min 34s / no limit).

re enabled, i updated the systemd service to ignore the return code of the welcome screen (i think this is what blocked the startup)

It works with the latest changes.
