gen/ just keeps the (current version of) decompressed metadata, right?
Why can't we update the files there?

> copy/share our data needs to work out what to replace ???? with.

"????" = (old)primary.xml.bz2 + (chain of)primary.xml.delta.bz2
As long as gen/primary.xml satisfies openchecksum, users should
not care about "????"...

note: if you (in the current Yum) rm primary_db.sqlite.bz2 but
keep gen/primary_db.sqlite, we DON'T re-download the compressed
file, too. As long as openchecksum matches, nobody should care..
