Bug#571438: Does not set up root device on boot

[Brad Jorsch]

Package: dmsetup
Version: 2.02.54-1

The udev rules provided by this package set a number of environment
variables on dm devices, which in turn are used by other applications
like devicekit-disks. On my system, where / is on an LVM logical volume,
these variables do not get set for that device; see the attached session
transcript for details.
