There is no rule that says there cannot be more than one default - as is
clear because it was possible to set up more than one default route to
begine with! And the error message, "File exists," does not seem to be true
at all, or pertinent. I was not asking to create a file, but a route. 

So I take it that the "ip" utility doesn't follow standard procedures and
practices regarding syntax and error messages? Why has this been allowed in
code that is integrated with the Linux kernel? Was Linus sleeping?
