tey are not network mounted. They are floppies in my case. But this is the
only case how to allow users from window applications to force mount via
automoutner. I use manual mounts for now.

direct maps? You mean:
a -fstype=auto,sync :/dev/fd0
c -fstype=vfat :/dev/hda1
d -fstype=ntfs :/dev/hda2
e -fstype=iso9660,ro,nodev,nosuid :/dev/hdb
This doesn't work - create any directories. I still need explicit entering
directories or symlinks.

Well, i really saw in TODO this:
autofs v5 TODO list
-------------------
* visible mountpoints
I think that is exactly what I need...
