Review: Needs Information

I think this is mostly OK, but the set of Commands files on cnf-extractor.internal seems a little excessive:

$ rsync -v cnf-extractor.internal::cnf-data/disco/main/cnf/

This depends a little on how the client is going to deal with it, but I don't think we should need the uncompressed files (noting that Launchpad with your branch will already deal with putting the uncompressed checksum in InRelease given only a .gz or .bz2 file).  With a fairly small extra tweak to Launchpad we might only need the .xz file.  What does the client actually use?
