Bug#458524: debian-edu-config: Left behind obsolete init.d script and other conffiles

[Petter Reinholdtsen <pere@hungry.com>]

Package: debian-edu-config
Version: 0.415
Severity: important

By coincident I discovered that discover-data had an obsolete init.d
script loadcpufreq laying around.  It should have been removed from
the disk when the script was dropped from the package, but wasn't:

  minerva:/# dpkg-query -W -f='${Conffiles}' debian-edu-config|grep init.d|grep obsolete
   /etc/init.d/loadcpufreq 5cf8c5572d789beaf18d79fc52f95665 obsolete
  minerva:/# md5sum /etc/init.d/loadcpufreq
  5cf8c5572d789beaf18d79fc52f95665  /etc/init.d/loadcpufreq
  minerva:/#

It should be removed if the md5sum patches the one in the package.

Here is an example from sudo.preinst on how to do this:

#!/bin/sh
rm_conffile() {
    PKGNAME="$1"
    CONFFILE="$2"

    if [ -e "$CONFFILE" ]; then
        md5sum="`md5sum \"$CONFFILE\" | sed -e \"s/ .*//\"`"
        old_md5sum="`dpkg-query -W -f='${Conffiles}' $PKGNAME | sed -n -e \"\\\\' $CONFFILE's/.* //p\"`"
        if [ "$md5sum" != "$old_md5sum" ]; then
            echo "Obsolete conffile $CONFFILE has been modified by you."
            echo "Saving as $CONFFILE.dpkg-bak ..."
            mv -f "$CONFFILE" "$CONFFILE".dpkg-bak
        else
            echo "Removing obsolete conffile $CONFFILE ..."
            rm -f "$CONFFILE"
        fi
    fi
}

case "$1" in
install|upgrade)
    if dpkg --compare-versions "$2" le 1.6.8p12-5; then
        rm_conffile sudo /etc/init.d/sudo
        update-rc.d sudo remove
    fi
esac

The init.d script is not the only obsolete conffile left behind by
debian-edu-config.  Here is the output from

 dpkg-query -W -f='${Conffiles}' debian-edu-config|grep obsolete
