Linux/PPC Installer Source Code

Is the source code available for the Linux/PPC 1999 installer (based on
the Red Hat installer)? I've scoured the Linux/PPC 1999 CD and can't seem
to locate it among the other source code and SRPMs.

I'm particularly interested in looking at loading software onto "virgin"
embedded boards and/or field upgrade strategies for embedded boards with
semi-frequent software upgrade requirements.

Thanks,

Grant Erickson
