Ok, so it seems it is completely chaotic -

As in RHEL/Fedora there is largely hacked  mpath udev rule file,
which is then responsible for using partx?

While in SUSE this seems to be handled by broken old unmaintained  kpartx udev 
rules file (as the file is useless - wondering how could do anything useful on 
SUSE)

AFAIK seems we miss communication between Ben with Hannes here :)

As logically it seem  calling  kpartx rule calls belong to  kpartx package.
However  kpartx upstream rule file is for  systems  from 2007 year.

So I'd have assumed lots of current mpath  RHEL rule patches should be
relocated to kpartx rules.

Leaving this to you guys...
