Bug Description
edubuntu beta2 usb live - 20120328
I create a second administrative user besides edubuntu
I have two partitions on my hard disk: ntfs and ext4
Login as edubuntu, I do not mount the ntfs partition, logout and login as the second user: the ntfs partition can be correctly mounted
I shut down and reboot the system
Login as edubuntu,I mount the ntfs partition, logout and login as the second user: the ntfs partition cannot be mounted because seems to be busy.
Please see the contents of my mount commands:

Mount is denied because the NTFS volume is already exclusively opened.
The volume may be already mounted, or another software may use it which
could be identified for example by the help of the 'fuser' command.

N.B. No problem with ext4 file system

I mean: nor ext4 file system is unmounted, but it can be used because not in exclusive use of edubuntu.

I test the situation in my installed 11.10 Ubuntu system and experience the same problem!
It seems that the first user who mounts the ntfs partition becomes its exclusive owner.
