[Bug 596271] [NEW] umount with UUID

[Carnë Draug]

Public bug reported:

Binary package hint: util-linux

Ubuntu version: Ubuntu 10.04 LTS
util-linux version: 2.17.2-0ubuntu1

It is not possible to umount a filesystem by specifying the UUID as it
is done with the mount command.

Example:

##Line of fstab
UUID=f6d4ad9e-f0d4-44ff-b878-a75f817e3d50 /mnt/backup     ext4    rw,suid,dev,noexec,noauto,nouser,async 0       2

## mount works fine
$ sudo mount UUID=f6d4ad9e-f0d4-44ff-b878-a75f817e3d50

## umount gives error
$ sudo umount UUID=f6d4ad9e-f0d4-44ff-b878-a75f817e3d50
umount: UUID=f6d4ad9e-f0d4-44ff-b878-a75f817e3d50: not found

This also happens in debian testing with util-linux version 2.16.2-0
