Rob,

Thank you for your response.  I also saw that comment in the docs; however, I am actually not interested in knowing what gnome_enable="YES" does.  I should have been more clear.

I would like to learn more about how rc operates.  I want to know where on the hard drive the instructions are located that activate when I say gnome_enable="YES".  I naively thought I would find a file called "/usr/local/etc/rc.d/gnome" -- but I did not.  Something more complicated is going on.  So my question is -- how is this working?

Thank you,

Chris
