Comment 6 for bug 430121

Tormod's log confirms that the upgrade failure happened with the old upstart, so I'm marking this as fixed in upstart. Changelog for the fixing version of the package:

upstart (0.6.3-4) karmic; urgency=low

  [ Scott James Remnant ]
  * Reduce the priority of the stopped by/continued by messages so that
    they are only shown when --verbose on the kernel command-line.
    LP: #401333.
  * Add a hack to look for /dev/.initramfs/*.pid files on startup and
    "fake" start jobs of those names. Basically this means that "status"
    and "stop" work for things like bootchart and usplash.
  * Implement a "reload" command in initctl that retrieves the current pid
    of the job and sends it the HUP signal. LP: #433544.

  [ Steve Langasek ]
  * debian/upstart-job:
    - give proper policy-compliant behavior of the start command: detect if
      the job is already running using upstart status, and if so return success.
    - same for the stop command: return success if the job is already stopped.
    - when $DPKG_MAINTSCRIPT_PACKAGE is set, don't spit warnings out because
      it's not the user's fault - we're being invoked by a maintainer script.
