That's really the recommended way to do it. If the software being configured 
supports it, another way is to set it up to read all configuration files from a 
directory and then you can simply install a new file into that directory from 
the other recipe (e.g. Apache is usually configured to read all configuration 
files in /etc/httpd/conf.d or similar).

Cheers,
Paul
