It all depends on the satisfaction of the testers.

Let's review the current situation with regards to files touched by the package

* /etc/multipathd.conf :

you only need to create one if you use multipath aliases or have hardware not
known internaly
its synthax is not yet fully stabilized : for example, I may decide to move from

multipath {
  wwid = 00000acdefg123456ff
  alias = system


multipath 00000acdefg123456ff {
  alias = system

also expect a few keyword additions to cover the new reinstate feature of the
kernel driver.

* /etc/hotplug.d/scsi/multipath

dead and to be removed from 0.3.0 and up

* /etc/dev.d/block/multipath.dev

this is where we call multipath and kpartx when nodes appear in /sys/block
this one should not change too much, but I expect more feedback from testers

* /etc/udev/udev.rules

from 0.3.0 and up, we don't touch it anymore

* /etc/udev/rules.d/multipath

maybe misnamed. I may rename it to device-mapper.
this is where I drop the devmap_name rule to alias dm-* devmaps with the devmap
name as shown by dmsetup

* /etc/mkinitrd/scripts/01_udev

optional, debian specific, but should be portable to other distribs

these copy udev, multipath tools and config files to initrd when mkinitrd is
01_udev also creates a script to fire up udevstart from initrd.
udevstart triggers the hotplug chain-reaction that leads to multipaths being

this certainly needs refining, and I expect distrib packagers to show interest
in taking them over. Do you ?

hope it clarify things,
