Are you creating your own CDs using a 'make release' (see release(7)) 
process? If so, I've generally followed an approach similar to the 
following:

1. Create your install.cfg file in the /usr/src/release/ directory.
2. Create a patch file that will add your install.cfg to a standard
    /usr/src tree:

      cd /usr/src
      diff -u /dev/null src/release/install.cfg > ~/local.patch

3. Make the release with the appropriate LOCAL_PATCH parameter:

      make release \
        CHROOTDIR=/some/dir \
        BUILDNAME=6.0-MYRELEASE \
        CVSROOT=/usr/home/ncvs \
        RELEASETAG=RELENG_6_0 \
        LOCAL_PATCHES=/path/to/local.path

That would build a 6.0 security branch build with your install.cfg in 
/usr/src/release/ of the chroot. The make release process then takes 
care of placing the install.cfg in the appropriate location on the CD.


If you're attempting to patch an existing CD image, reading 
/usr/src/release/Makefile suggests you'll need to:

     - Extract the contents of the ISO
     - Un-gzip and then mount the decompressed /boot/mfsroot.gz file
     - Place your install.cfg in the root of the mounted mfsroot fs
     - Unmount the mfsroot filesystem
     - Re-gzip the mfsroot file to /boot/mfsroot.gz
     - Run mkisofs to re-create the CD

Hopefully this points you in the right general direction!
