Replace (silently) duplicate keys

makemap command-line switch

Ordinarily, it is an error to specify a key that already exists in a database. That is:

 john   john@host1 john   john@host2 

Here, instead of replacing the first with the second, the second john line produces an error. To allow replacement keys, use the -r switch with makemap . Generally, the -r and -o switches should be combined when updating a database with new information. (See also the editmap program, Section 5.2.)
