You'd be better off fixing whatever it is that is making your host IDs  
change, but I suppose you  could also try to create a zero-length  
known_hosts file, and keep it that way via:

   chflags uchg ~/.ssh/known_hosts

You might also try to automate finding the current valid hostkeys via  
ssh-keyscan.
