Intention of this patch is fixing postinst failure. I have no idea
what this file is for. Can somebody give me a hint (is it required in
systemd environments?) and can we fix this in another series?
By the way: I am not using gdm. From what I have seen during tests for
this series it needs a lot more love to work as expected:
* gdm decides to put my standard user into the list of excluded users
so it is not displayed in the list and has to be entered manually.
* it is terribly slow
* the log files are full of different warnings - one thing I saw was
that polkit-gnome does not find its way into the image although it is
recommended
