Comment 14 for bug 767498

For reference, in 1.14.1-0ubuntu8.1 you have this:

# Automatically added by dh_installinit
if [ -e "/etc/init/apport.conf" ]; then
        # start fails if already running
        start apport || :
fi
# End automatically added section

while in 1.20.1-0ubuntu3 you have this instead:

# Automatically added by dh_installinit
if [ -e "/etc/init/apport.conf" ]; then
    invoke-rc.d apport start || exit $?
fi
# End automatically added section

I'm not sure, but that looks like a regression to me, moving away from upstart's "start" to "invoke-rc.d", so it may have come from old code. The old code hypothesis is kind of confirmed by the bad idea of exiting with a non-zero code in a postinstall script for no good reason when the 10.10 package just didn't care if the script failed.
