Adding custom RPMs to an NFS install setup

Hello everyone. I've set up an NFS install for SLES 8 & SuSE 8.1 according to chapter 6 ofAutoYast2 guide: http://www.suse.de/~nashif/autoinstall/8.1/autoyast2.pdf I am unclear how to modify this setup to install custom RPMs that I have created and need installed on workstations. Anyone done this? Thanks.
