Title:
  ntfs file system NOT unmounted

Status in “util-linux” package in Ubuntu:
  New

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.
