I'm assuming that you're referring here to getting zchunk packaged into
Fedora. I'd really like to finalize the file format (we're close, but
I still need a good way of storing signatures in it) and the download
API before releasing it into Fedora proper.
I'm looking forward to this!
I would recommend using the dicts mentioned above as they give me
40% space savings for both other.xml.zck and primary.xml.zck. Do
please let me know if you run into any problems.
Are those dictionaries Fedora specific? If so, how can other
distributions generate similar ones? If not, still, how were they
