Affects: gnome-vfs2 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Now all partitions are shown in "Computer" as removable drives, I guess
to provide a place to mount/unmount them easily.

Well, this does not work with dmraid volumes: the individual partitions
are shown (for example /dev/sda1 and /dev/sda2) but not the dmraid
volume (/dev/mapper/whatever1). It is likely that the useful partition
to show is the dmraid one.

So i think that:
  - dmraid partitions should be shown
  - Individual partitions forming the raid should be hidden by default and/or an option should be given to hide/show individual partitions in "Computer".
