Thanks, that helped!

I was reading the manpage on my debian box, which is using
udev-125 and thus the documentation is horribly outdated
in some parts, i.e. I was still under the impression --action­d
was the default.

Thanks for the help, now everything works like a charm and I
can think about the proper mount script/command.
