I've done that (well, minus NFS). I can easily enough install without
the second DVD ISO, as the servers won't have openoffice anyway.

My question was more a point of curiosity. I supposed I could have said
"how can I merge the two ISOs into one" and gotten matching answers. So
then, the real question is; How can I recreate the package list that is
found in the ISO that anaconda uses to know what packages are available?
