Fix for the problem Eric reported for this topology:
uav <---> distrib <---> display ^ ^ ^ +-----------+-------------+---> namer where tmcd was returning multiple aliases since there were multiple links between nodes. Thats been a bug for long time, but its very rare to have two links between the same two nodes, and so I never bothered to deal with it. I have "fixed" it, but the fix is very unsatisfying since the choice it makes is not consistent. For example, on distrib the ideal choice is to create aliases for the lan links, but instead I get a mix; one alias is for the duplex link to uav, another to the lan link to display. To make it select a consistent set, it will take even more hackery in tmcd, and I am not in the mood for it right now, given how rarely this happens. At least the host file is now "correct."
