You're going to pretty much instantly download the complete filelists then 
b/c if you add ANY 3rd party repo you're going to need /bin/sh probably 
immediately along with various and sundry items in /etc/.

Now - an argument could be made for nuking /bin/sh deps from orbit but 
that's going to have to happen at another layer than this.

1. a lot of our mirrors won't want to run any app
2. some of our mirrors are not running on linux (or sometimes not 
even on a unix)
3. it makes 'mirroring' things much harder in the traditional sense
4. yes you need to sign it otherwise you'll get the same set of problems 
we just dealt with last fall. We have to sign the metadata to make sure 
clients aren't screwed.
