The TKLPatch conf file below does not seem to be making any lasting changes to /etc/bash.bashrc file!

Any suggestions as to how I can append the required info to a file while making in new ISO?

Thanks

    apt-get update
    DEBIAN_FRONTEND=noninteractive apt-get -y \
        -o DPkg::Options::=--force-confdef \
        -o DPkg::Options::=--force-confold \
        install $@
}
