True, but the way our build process, repo layout and mirroring system
work, if you want to leave a bit of Fedora out when you're mirroring
it, this is not easy. rsync bundles can't really do the job in cases
like this, because of how they're based on directory structures
combined with how we structure our repos. Mirrors have to use some kind
of script with a filter to do this; quick-fedora-mirror helps, but you
still have to maintain and write the filters. My mirror currently
rejoices in this:

FILTEREXP='(/i386/|/armhfp/|/aarch64/|/source/|/SRPMS|/debug/|\.iso|\.qcow2|\.raw\.xz|\.box|/releases/test|/22/|/23/|/24/|/25/|/26/|/27/)'


to try and reduce the amount of bandwidth it eats. Which is of course
fun to remember about and maintain. And hey look, indeed I haven't, cos
I didn't add 28 to it yet...

Of course we could completely rearrange how we build and store things,
but...see under 'human resources' :)
