Do you mean that SimFactory should abort if it is there, or that we should ask people not to use .cactus/config?  People might not remember that they have it there, especially as it is a hidden directory.

I suspect that it is merging them.  In that case, I think simfactory should complain very loudly if there is a ~/.cactus/config file, as the options you are using will be a mixture of the optionlist configured for the machine and the one in ~/.cactus/config.  I'm still dubious about the benefit of having ~/.cactus/config.  I think it is used rarely enough by the main developers that it probably isn't tested well, and issues like this tend to get overlooked.
