this seems to imply you want me to create a file named <hostname>.mc.  The 
instructions I followed in the handbook also mentioned that, "Many 
administrators choose to use the output from hostname(1) as the .mc file for 
uniqueness."  Do I have to make this new file, paste into it all the stuff 
in "freebsd.mc" and then add these lines too?
