[Bug 1363519] Re: start-stop-daemon fails debsums check

[Adam Conrad]

** Description changed:

+ [ SRU Justification ]
+ Currently, systems installed from live media have several critical files (like initctl and start-stop-daemon) failing debsums checks because they are incorrectly using the files from the release pocket versions of their packages, rather than the -updates version that's actually installed.
+ 
+ [ Test Case ]
+ Build a test CD, run through an install, and verify that, post-install, all the files referenced in the patches are the expected content.  Those files are:
+ 
+ /sbin/initctl (should be from the -updates version of upstart)
+ /sbin/start-stop-daemon (should be from the -updates version of dpkg)
+ /bin/hostname (should be from the release pocket version of hostname)
+ /usr/sbin/policy-rc.d (should not exist on the filesystem, post-install)
+ 
+ [ Regression Potential ]
+ Assuming the above test case passes, pretty minimal.  The change isn't invasive, except for swapping silly mv && do_stuff && mv semantics with more correct dpkg-divert add/remove.
+ 
+ [ Original Report ]
  After fresh install from 14.04.1-amd64-dvd - debsums -c results in: /sbin/start-stop-daemon. I checked dpkg package with dpkg -s dpkg and got: Status: install ok installed, Version: 1.17.5ubuntu5.3 (the latest version) but when I did md5sum /sbin/start-stop-daemon, I got b1b8894ae2e3b547dca0e288634cce4a, which is md5sum for start-stop-daemon from dpkg version 1.17.5ubuntu5!
  I confirmed the problem in Ubuntu/Xubuntu 14.04.1-i386 (VirtualBox) - the same case - latest version of dpkg package contains older version of start-stop-daemon. I guess this is the same problem I reported here: https://bugs.launchpad.net/ubuntu/+source/live-build/+bug/1150737. I fixed the problem with sudo apt-get install --reinstall dpkg - simple if You know about it, otherwise You have outdated/buggy/ package/system...
  Rgds!
