If the file's part of CONF_FILES and the checksum changes, it should never be 
deleted/overwritten by any subsequent package removal/install. How about an 
INSTALL script that deliberately touches the file in order to change its 
checksum? It's a little on the dirty side, but probably the easiest way right 
now.
