Thanks very much Jess.

The easiest way is probably as a merge proposal.  You can download the
bzr tree for the package,

bzr branch lp:ubuntu/natty-updates/multipath-tools

Or, for the current release (oneiric)

bzr branch lp:ubuntu/multipath-tools

Make your changes in the multipath-tools directory, commit them, push
them back to launchpad,

bzr push lp:~jessyjohnson/ubuntu/natty-updates/multipath-tools/fix-
kpartx-rules

(Or whatever your lp username is in place of jessyjohnson)

and then do a merge proposal by opening up the web page

bzr lp-open

And choosing 'propose for merge' from that web page.

The info for the multipath-tools upstream is at

Title:
  kpartx udev rule is broken

Status in “dmraid” package in Ubuntu:
  In Progress
Status in “multipath-tools” package in Ubuntu:
  In Progress
Status in “multipath-tools” package in Debian:
  New

Bug description:
  Binary package hint: multipath-tools

  The kpartx udev rule looks like this:

  ENV{DM_STATE}=="ACTIVE", ENV{DM_UUID}=="dmraid-*", \
          RUN+="/sbin/kpartx -a -p -part /dev/$kernel"

  This kpartx command should not be run because dmraid already creates
  the partition device, but it isn't run anyhow because the rule matches
  on "dmraid-*" but dmraid devices have an id of the form "DMRAID-*".
  Note the difference in case.
