Installing minimal number of packages

[Michael <michael kmaclub com>]

Hello,

I am doing a fc6 install for testing an automated app server install.

In the packages section, I just have

%packages
@core
sox
screen
mysql-server

I would expect a few small number of packages ( around 100 ).  However, 
I am getting 550 installed.  I don't really understand why so many 
packages are getting pulled in.

How can I debug this?  Is @core no longer the right directive?
