I just tried yesterday. Remember, I was the one that posted on the
other thread "media:/ shows unnecessary media" about media not
mounting my harddisk :) So no, it doesn't work. Plus, pmount complains
about hdas not being removable media, so one of the big issues here is
that pmount will *not* work with hard disks. Maybe it will if they are
recognized via the hotplug/udev interface, but I don't know.

Therefore you are ;)

Just skip that partition? :)

I will try and do it later today.

Hm. Hope Kubuntu live has those deps :)

But it should only happen if it wasn't configured already ...
otherwise just a popup notice to let the user know the device has been

That's an interesting idea. Are there Kubuntu-specific feature that
allow that, or can the scripts and all be passed upstream with little
