    Switch to using debugreiserfs to read the UUID (#684115)
    
    For a mounted reiserfs file system with a Nil UUID (all zeros) GParted
    will display a partition specific warning.  This comes from the reiserfs
    specific read_uuid() method.  Error demonstration:
    
        # blkid /dev/sda15
        /dev/sda15: LABEL="test-reiserfs-2" TYPE="reiserfs"
        # mount | grep sda15
        /dev/sda15 on /mnt/2 type reiserfs (rw,relatime)
        # reiserfstune /dev/sda15
        reiserfstune: Reiserfstune is not allowed to be run on mounted filesystem.
    
    Switch to using debugreiserfs to read the UUID as it can be used on a
    mounted file system.
    
        # debugreiserfs /dev/sda15 2> /dev/null | grep UUI
        UUID: 00000000-0000-0000-0000-000000000000
