For those who don't know rsync or mkisofs well, but want to make daily dvd isos of rawhide, and as a side benefit have a local yum repo, I wrote a script for you.
ftp://people.redhat.com/ckloiber/FedoraSync.sh
Usage: FedoraSync.sh <options> <arch> <source_repo> <local_directory>
Options:
-live No changes are made to the local copy without this. -del Passes --delete to rsync, files not existing at the source are removed in the local tree. -paranoid 'touch' all local files, makes rsync verify them and avoids corruption. Takes a little longer, but I highly recommend it.
-iso After rsync is complete, create a dvd iso from the local tree. *Note: -iso enables -live, -del, and -paranoid
-ssh Passes -e ssh to rsync, so you can use rsync over ssh connections.
arch is one of: i386, x86_64, or ppc (ppc untested)
Options can now be given in any order, or ommitted to use built-in defaults.
I recommend you start by copying your latest CD's or DVD to /var/ftp/pub/rawhide/$ARCH, (as that is the default local directory my script uses) then run the script to update that copy to save on bandwidth a bit.
Enjoy, but please use an rsync mirror near you. As configured it will use rsync://mirror.linux.duke.edu/fedora-linux-core-development but we don't want to overload that mirror. Other rsync mirrors can be found at:

You may have to hunt a bit for the right path at first. When you get it right, running it with just -del will show which old files will be deleted, and which will be created. You should not see the arch in the path of any output. You will see Fedora, isolinux, headers, etc at the beginning of the test output. Running with -live (or -live -del -paranoid) will update the local tree, but not make an iso. Using -iso will enable -live -del and -paranoid automatically, and build an iso suitable for booting (Yes, it works for me on both i386 and x86_64). Speaking of x86_64 you can override the arch of the system running the script to download and burn an x86_64 iso. You might be able to make an iso for ppc, however I doubt it will boot unless isolinux is supported there as well. (I have not tested ppc at all as I don't have one. If you make it work, send patches!)
As a side benefit to all this, the yum headers get downloaded and placed in your anonymous ftp tree, as well as on the DVD iso. You can then use either as a local yum repository, further saving bandwidth if you have many machines to update.
Have fun, I am. :)
