Comment 9 for bug 444500

Nope, it does not seem so.
As for the labelled partitions (#442130): [cite]a workaround is to specify the partitions by /dev/sdXXX[/cite];
and here with cifs mounts, the only way to get the duplicates off is not to specify them at all.

BTW. There is a "step up" in Natty: one record in fstab (say: //server/share /media/share cifs) is enough to get the duplicated icons in computer://, thus testing is now easier. ;-)
