[Bug 523688] Re: postinst calls start(8) instead of invoke-rc.d(8), ignores policy-rc.d(8).

Acting the same as https://bugs.debian.org/571054

Maybe the reasons can be considered different: the problem does not hold
anymore, it's quite old and the affected releases are EOL.

Title:
  postinst calls start(8) instead of invoke-rc.d(8), ignores policy-
  rc.d(8).

Bug description:
  policy-rc.d(8) can be used to prevent sysvinit services from booting.
  This is particularly important within chroots.

  In Debian Sid, I used pbuilder(8) to create a lucid "base.tgz" chroot.
  I then used pbuilder --login to get a shell, and ran "apt-get install
  apport".  (I had heard that apport didn't just fire up a web browser,
  and so I was trying to use it to report a bug in lucid's kernel.)

  To my surprise, I found the postinst was trying to start a service:

      Setting up apport (1.12-0ubuntu5) ...
      start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused

  Luckily it failed, because I wasn't running upstart outside the
  chroot.  But it seems to me that either upstart's start(8) should
  either honour policy-rc.d, or at least reinvent it.

  I see five things that could happen here:

   - I've misunderstood the error message. Flag MOREINFO.

   - upstart already has a policy-rc.d equivalent, and apport needs to
     be told to honor it in apport's postinst.  Assign to apport.

   - upstart already has a policy-rc.d equivalent, and pbuilder needs to
     be told to create the appropriate "deny all" policy when creating
     Ubuntu-based chroots.  Assign to pbuilder.

   - upstart has no policy-rc.d equivalent, and needs to grow one.
     Assign to upstart.

   - upstart has no policy-rc.d equivalent, and the upstart developers
     think it doesn't need one.  Flag WONTFIX and I get grumpier.
