If you are using CentOS here is what I recommend:

1. Mount a CentOS ISO. 
2. Copy the contents of Packages/* to a location you put in CONFIG_REPOS.
3. Repeat steps 1 & 2 for each ISO image (eg 2 for the DVD images).
4. Change into the directory you copied the packages to.
5. Run "createrepo -d ."
6. You are ready to roll your installable image.

Note: CentOS archives previous releases.  Currently Tresys is testing against
RHEL 6.2 (this may have changed though).  To get a specific archived ISO from
the CentOS mirrors use their "vault" sub-domain.  Eg:
- http://vault.centos.org/6.2/isos/x86_64/
