[Bug 634387] Re: creates motd.tail on postinst, which could mean duplicate entries in /etc/motd

[nutznboltz]

Now all the /etc/motd.tail files have been clobbered by overwriting them
with garbage for the second time thats to this:

sysvinit (2.87dsf-4ubuntu17.3) lucid-proposed; urgency=low

  * debian/sysv-rc/sbin/invoke-rc.d: replace RUNLEVEL with RUNLEVELHELPER.
    Using RUNLEVEL causes spurious failures when invoke-rc.d is invoked
    with RUNLEVEL already defined in the environment (as it is e.g. during
    bootup) since invoke-rc.d's RUNLEVEL will become an exported variable
    at that point and cause /sbin/runlevel to return bad data. (LP: #619246)

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...
