Public bug reported: The 'mv_conffile' function only works if the target file exists by the postinst stage.
This means the function doesn't support those packages where the new configuration file is optional and may not exist at postinst stage. The case in point is 'iptables-persistent' where the new 'rules.v4' may not exists after installation. Bug #967018 A simple guard in front of the 'mv' command would add support.
