Bug#755359: [kdm] systemd seem to fail to start display-manager.service

As I said, that was a test system and there was only KDM installed,
nothing else. I have to poke around a bit more. However, it seems ...

that this symlink is actually always created by the postinst script of
the display manager (on Debian, Fedora uses the [Install] section of
the .service file for that by setting an alias to
display-manager.service) and looking at the source code of the kdm
Debian package, this particular part is actually missing in the kdm
package while it is present in the lightdm package. So it's actually a
bit surprising that the link was installed on my test system.

Yes, this is actually the basic idea.

It actually depends on which package you reconfigure. So, if you run
"dpkg-reconfigure lightdm" (provided that lightdm is installed) and
choose "kdm as your default DM, it should work. However, if you do
that with "dpkg-reconfigure kdm" and choose "kdm" or any other DM for
that matter, it shouldn't work.

Thanks!
I will dig a bit more into the source code of the kdm Debian package
and see if I can provide an updated version which should finally
provide 100% compatibility.
However, just to be sure I'm asking again: When you do a fresh
installation and don't use a service file for kdm, kdm works and
"systemctl status kdm.service" shows that it's running however you get
the warning in the journal about the display-manager service, right?
Cheers,
Adrian
