Actually, I was looking at revsion 114...

... but then again, I see that that revision is dated 2009-06-25, so I
guess it's not actually the source code for the version that is
included in Oneric, anyway.

So... I downloaded the tar.gz file for sysvinit-2.87dsf-4ubuntu25, and can
confirm that the initscripts.postinst no longer creates the motd.tail
file.

Title:
  creates motd.tail on postinst, which could mean duplicate entries in
  /etc/motd

Status in “sysvinit” package in Ubuntu:
  Confirmed
Status in “sysvinit” package in Debian:
  Unknown

Bug description:
  Binary package hint: sysvinit

  Did an upgrade on a server (8.04 -> 10.04), and after a reboot & login
  noticed that motd had duplicate headers:

  traced it down to the postinst files of base-files and iniscripts.
  First, base-files moved motd.tail as motd.tail.old, and later
  initscripts would create a new on by running 'sed 1d /etc/motd >
  /etc/motd.tail' (motd would by that time have been regenerated it
  seems). The result after a login is above.

  I can't think of a reason why initscripts creates motd.tail in the
  first place. In ubuntu the file should be empty, or nonexistant...
