Confused about %config file section directive

[russell cecala]

Hi,

I want to create two RPMs.  The first RPM install apache and I call it my-apache.rpm and a second my-apache-config.rpm.  my-apache.rpm installs apache and my-apache-config.rpm adds some files like /usr/local/apache/conf/extra/my.conf but I also want it to overwrite my-apache.rpm's /usr/local/apache/conf/httpd.conf with a custom httpd.conf

In my-apache.spec I used these lines:

%files
...
%config /apps/SD/apache/conf/httpd.conf

but when I attempt to install the RPM via YUM I get an error 

Transaction Check Error:   
  file /usr/local/apache/conf/httpd.conf from install of my-apache-config conflicts with file from package my-apache

I tried not using the %config directive and had the same result.  How can I specify in my spec file that it is OK to overwrite a file?
