If you look at the 4th linue in .diskinfo:

1064433227.893006
Fedora Core 0.94
i386
1,2,3
RedHat/base
RedHat/RPMS
RedHat/pixmaps

I'm pretty sure represents which CD images are present on the current
media. My script counts the number of CD's it's processed, and adjusts
the 4th line to reflect the number of CD's present. The SRPMS disks
apparently don't need to be listed there, but don't hurt either. I have
not dug deep enough to tell you what that mysterious first line means,
but if I copy it it just works. With an FTP-style directory, I just have
to hope the .discinfo exists and is correct, which is why I say my
script is a hack.
