Please include installation media build number in installation logs

For desktop installations, which are probably the most common, I have found the following code useful to extract the disk information from the casper.log:

        # Found label 'Ubuntu 8.04.1 _Hardy Heron_ - Release amd64 (20080702.1)'
        distributor_regex = r"(?P<distributor>[\w\-]+)"
        release_regex = r"(?P<release>[\d\.]+)"
        codename_regex = r"(?P<codename>[^_]+)"
        official_regex = r"(?P<official>[\w ]+)"
        architecture_regex = r"(?P<architecture>[\w\+]+)"
        type_regex = r"(?P<type>Binary-\d+)"
        date_regex = r"(?P<date>[^\)]+)"

        info_regex = r"%s %s _%s_ - %s %s (%s )?\(%s\)" % (distributor_regex,
            release_regex, codename_regex, official_regex, architecture_regex,
            type_regex, date_regex)
        line_regex = r"Found label '%s'" % info_regex
        line_pattern = re.compile(line_regex)

        file = open("/var/log/installer/casper.log")
        for line in file.readlines():
            match = line_pattern.match(line)
            if match:
                print match.group("codename")

This bug was fixed in the package installation-report - 2.39ubuntu2

---------------
installation-report (2.39ubuntu2) karmic; urgency=low

  * Write /cdrom/.disk/info to /var/log/installer/media-info
    (LP: #364649).

This bug was fixed in the package ubiquity - 1.99.29

---------------
ubiquity (1.99.29) karmic; urgency=low

  [ Colin Watson ]
  * Use a separate PROGRESS REGION for each install plugin (LP: #438979).
  * GTK frontend:
    - When switching language, translate other top-level widgets (dialogs)
      and their children, as well as the main notebook pages (LP: #441622).
  * Install a dummy initctl similar to the dummy start-stop-daemon while
    doing anything that might install or remove packages in the target
    system, so that attempts to control Upstart jobs won't do anything.
  * Stop Upstart jobs when switching to runlevel 0 or 6, which I think fixes
    repeated respawns on shutdown (LP: #432140).
  * Save /var/log/installer/debug to the target system if it exists.
  * In the auto-resize bar, use the preferred partition size requested by
    partman-auto/partman-partitioning, rather than hardcoding the maximum
    size or making up our own (LP: #421407).
  * Update imported translations from gtk+2.0 2.18.1-1ubuntu1 (adds Asturian
    and Bengali).
  * Update translations from Launchpad.
  * Automatic update of included source packages: apt-setup 1:0.41ubuntu2,
    console-setup 1.34ubuntu4, flash-kernel 2.13ubuntu12, grub-installer
    1.43ubuntu5, partman-partitioning 72ubuntu2, partman-target 64ubuntu2.

  [ Evan Dandrea ]
  * Port fix for return_to_partitioning from the GTK+ frontend to the
    KDE frontend (LP: #439184).
  * Explicitly depend on reiserfsprogs so that we don't have to add it
    to every live seed (LP: #431976).
  * Write /cdrom/.disk/info to /var/log/installer/media-info
    (LP: #364649).

  [ Roman Shtylman ]
  * Limit width of side breadcumbs in kde for long translation text.
    Using elided text where needed (LP: #438918)

FYI, the corresponding changes to apport are in revno 1554 and should be included in the next apport upload following 1.9.2-0ubuntu1

------------------------------------------------------------
revno: 1554
committer: Matt Zimmerman <email address hidden>
branch nick: apport
timestamp: Tue 2009-10-06 15:58:45 +0100
message:
  general-hooks/ubuntu.py: Include in Ubuntu bug reports the version number
  of the installation media used to install the system, via
  /var/log/installer/media-info (cf. #364649)
------------------------------------------------------------

This bug was fixed in the package cdrom-detect - 1.32ubuntu2

---------------
cdrom-detect (1.32ubuntu2) lucid; urgency=low

  * Copy /cdrom/.disk/info to /var/log/media-info, in order that we get
    /var/log/installer/media-info on the installed system; doing this in
    save-logs is too late because /cdrom is already unmounted by that point
    (LP: #364649).
