Does it actually make sense for dpkg-trigger to see those environment variables when the postinst is not being run by dpkg? Seems possible that any deferred trigger processing it then sets up will not take effect until the next dpkg run, which could be well after dpkg-reconfigure finishes. Perhaps dpkg-reconfigure needs to call dpkg --configure --pending ? -- see shy jo
