[ ] run zsync from client on metadata from our server
[ ] disable normal fetching of metadata in DNF (self.demands.cacheonly = True)

[ ] figure out how to estimate actual download size of .zsync file and diff blocks (output of zsync should contain this info)

jsilhan commented 8 years ago

the logic should be following:

# if "updates" is in enabled repos
    # disable "updates" repo
    # run zsync on each file on the server hosting zsync files and relevant file in `repo.cachedir`
    # (all updated xmls should be inside /var/cache/dnf/updates-*)
    repo.md_only_cached = True  # for "updates" repo
