Creating an FTP site for installing packages

I have SuSE Linux 9.2 Professional on CD and DVD. It would be convenient to load the whole set of packages from CD on to a spare Solaris box, and then get YAST to load packages from there, rather than from the CDs. It seems as though this would be possible, but I can't find any instructions about what the directory layout has to be on the FTP server. Is this documented somewhere? Once I have created appropriate top level directories, I assume I just copy the CDs onto the server and ensure that an anonymous FTP client can read the files. Is that right? Thanks Nigel
