[Bug 900526] Re: d-i fails to divert initctl when upgrading packages during install

[Jean-Baptiste Lallement]

I installed the latest netboot image. 
I attached 2 screenshots:
1. just after the base system is installed. It shows start-stop-daemon (94 bytes), start-stop-daemon.REAL (28028 bytes), initctl (84bytes), initctl.REAL (114056 bytes) and dpkg (418216bytes April 15)
2. During installation after selection of "base server". It shows start-stop-daemon (94 bytes), start-stop-daemon.REAL (28028 bytes), initctl (84 bytes), initctl.REAL (114056 bytes) and dpkg (418216bytes Jan. 6)

Steve, Colin could you interpret these results or is there any
additional information I can provide ?

Bug description:
  TEST CASE: Run a netboot installation with apt-setup/proposed=true.
  Watch 'ls -l /target/sbin/start-stop-daemon* /target/sbin/initctl*'
  after the base system is installed and ensure that there's no period
  when both start-stop-daemon and start-stop-daemon.REAL (similarly
  initctl and initctl.REAL) are non-fake versions - you can tell by the
  size - and that if there's an update available for dpkg or upstart
  that the timestamp of the relevant binaries get updated.  In the hardy
  case, don't worry about initctl, and dpkg probably won't be upgraded
  but it's still worth checking that start-stop-daemon is diverted
  correctly.

  Regression potential: Checking whether installs with apt-
  setup/proposed=true work should be sufficient.

  Original report follows:

  The SRU verification for bug #771372 in maverick has revealed that
  debian-installer's chroot setup handling when installing/upgrading
  packages at install time is different than the chroot setup used by
  debootstrap.  When initially bootstrapping a maverick system, the
  postinst script of the maverick procps package has its call to 'start'
  successfully intercepted; however, when *upgrading* the procps package
  after debootstrap, the start call is not intercepted, resulting in
  install failures.

  Since this is impossible to fix in the maverick installer post-
  release, I'll backport the fix for bug #602896 in a subsequent procps
  SRU; but investigation is needed here to find out why d-i isn't
  handling initctl correctly and make sure this is properly resolved for
  precise.

  15:03 < cjwatson> chroot-setup.sh is supposed to divert initctl too
  15:08 < cjwatson> slangasek: There is something odd there, indeed.  I don't quite see what; visually, the code seems right
  15:08 < slangasek> cjwatson: should I raise a bug on debian-installer?
  15:08 < cjwatson> slangasek: yes please
  15:09 < slangasek> ok
  15:09 < cjwatson> (probably belongs on either pkgsel or debian-installer-utils, but debian-installer is the place to start)
