[Curtis Gedak <gedakc src gnome org>]

commit 87acba030c945d7a8cb5c69f045fc2914c1ed859

    Remove all usage of kpartx to avoid partition entry duplicates
    
    Usage of the kpartx package to create partition names has been
    completely removed.  Hence kpartx is no longer even an optionally used
    package by gparted.
    
    This change is related to the following bug report:
    
    Ubuntu launchpad bug 719129 - [Natty] Gparted duplicates dmraid
                                  partition devices
    https://bugs.launchpad.net/ubuntu/+source/gparted/+bug/719129
