as many do, i keep my source directories handy so i can do network installs for my systems. when i download a new set of .iso files, i just make some folder structure under the distro, and copy the contents within the .iso files into usually something like:

../fedora/core/4/i386/os

etc etc. well, im getting ready to do a new one, and i was thinking that it would be so cool if i could take all the update packages that have been released against fedora core 4, and switch them into the source repository. this way, my install is as fresh as could be, and no 'yum -y update' would be required.

anyone do anything like this, and if so, what all was involved to update your install sources?
