Bug#488223: udev rule to export "dmsetup export" information

[Guido Günther]

Package: dmsetup
Version: 2:1.02.26-1
Severity: wishlist

Hi,
the attached udev rule exports the information available via "dmsetup
export" for use by other udev rules. Since kpartx/multipath runs as
(z)60 this rule should run before that. There's some overlap with Bug
#455746.
Cheers,
