I've found the following to be quite a reliable way to modify the installation: First install the src package by issuing the command: rpm -ivh anaconda-7.3.7.src.rpm This puts the source tar-ball in /usr/src/redhat/SOURCE and the spec-file in /usr/src/redhat/SPEC Second untar the source with the command: tar xjf anaconda-7.3.7.tar.bz2 Make two copies of the unpacked directories, one with the original name, the other with your own addition, like anaconda-7.3.7 and anaconda-7.3.7-prasanna. After this make a copy of the spec-file with a similar naming ie. anaconda-prasanna.spec Now the objective is to create a patch from the difference of the original and the modified source-directory, add it to the modified spec-file and from that create a modified set of rpms to be installed and used to create new ISO-images. Most of the changes do not require python knowledge, for example if we want to replace the RedHat CDROM-path, we can do it by recursively replace the string RedHat/ in the /usr/src/redhat/SOURCE/anaconda-7.3.7-prasanna with the command find /usr/src/redhat/SOURCE/anaconda-7.3.7-prasanna -type f -exec \ replace "RedHat/" "Prasanna/" -- {} \; (The replace command comes with the mysql-packages and was quite a saver when I did this myself) After which we create a new patch-file with the commands: cd /usr/src/redhat/SOURCE diff -urN anaconda-7.3.7 anaconda-7.3.7-prasanna > anaconda-prasanna.patch And add the patch to the modified spec-file. Add the following row under the BuildRoot:-line Patch: anaconda-prasanna.patch And between the %setup-q and %build add the following line: %patch -p1 Also you can increase the release-number so the installation won't warn of existing packages, also you can add an identifier to the release-number (most distributions do this to differentiate the rpm from Red Hats). Now the new spec can be used to create new anaconda-packages, run the commands: cd /usr/src/redhat/SPEC rpm -ba anaconda-prasanna.spec And install the modified rpms from /usr/src/redhat/RPMS/i386/ directory. Also remember to copy and replace the anaconda rpm-packages to your installation-directory. BTW Changing all the places where Red Hat is mentioned is a bit more challenging, some of the po-files have the string split up on two lines, so it requires some manual work. Also be careful not to replace the addresses, as these usually are used in copyright texts. Here the grep-commands are helpful: cd /usr/src/redhat/SOURCE/anaconda-7.3.7-prasanna grep -r "Red Hat, Inc" * grep -r "Red Hat" * grep -r " Red" * grep -r "Hat, Inc" * In 8.0 you also need to make new versions of the comps-extras if you intend to change the CDROM-path.
