Well let's speak of triplicate names: The name zeus is used for three sites in New Jersey, Oregon, and Great Britain. I am getting a bit tired of adding -dxyz!non_singleton_offender to pathalias's makefile. Someday soon the command string will be too long to pass into the shell from make. One solution would be to modify pathalias to accept a dot in site identifiers but just output only the sitename before the dot (easy), AND modify all the non-singleton names in mod.map.uucp to the full domains (harder-best done once via cbosgd!map and its volunteers). I still wonder why the maps aren't adequately check for non-singletons before they are sent out, a simple script would show a small set of likely candidates. For example: produces: zeus.OR.UUCP x(DEMAND) x!zeus zeus.NJ.ATT.UUCP y(DEMAND) y!zeus zeus.HWCS.GB.UUCP z(DEMAND) z!zeus We could still have just: ihnp4 x(DEMAND), zeus.NJ.ATT.UUCP(DEMAND), .... ihnp4!x ihnp4!zeus for now, and switch all of the database over to domains with time.
