Ok... I didn't know a Binary called mountpoint. :) Now i know ist.

And a grep in /etc for "mountpoint" gave me

And tadaaa, "mountpoint" is the devil.
When i look on the result above, it could only be "init.d/mountnfs.sh"
so i try to deactivate nfs-mounts, and report what happens.

If this is true, what i thought before, then it's a fault in design. And
further u think it's a good aproach, that more intelligent people think
about this. Because I think I'm not the only one with this problem. And
a "noauto" in fstab should be exact this - even with automount-option.
