multipathd does not act upon udev changes -- its very easy to see when
running udev monitor and multipathd -v9 -d and then attaching new disks.
by the looks of it, support for monitoring events by libudev was only added in 2013, far later than 0.4.9
everything seems to exist in 0.5, and none of it was merged to Ubuntu, yet.
