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

[Colin Watson]

Light dawns.

chroot-setup.sh does indeed move aside /sbin/initctl.  However, it
doesn't divert it!  Therefore, if upstart is upgraded, it will put a
real initctl back.  In this case, upstart is upgraded before procps,
hence the bug.

Alarmingly, this means that in such cases the resulting system will end
up with an upgraded version of upstart according to dpkg but will in
fact have an old initctl binary, because d-i will have saved initctl
from the start of its internal upgrade process and then put it back at
the end.  Therefore, we need to fix this bug rather urgently for all
supported releases.

Bug description:
  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)
