is this an issue for opensuse? I know it's one for fedora b/c of wanting
folks to be able to search for pkgs based on summary/description info in
their own language.

Agreed - the thought was to have them all in a subdir with an index for
them so you could get them and use the same gpg/x509 verifier for them.


If you remove all the crazy you can make the full pkg metadata pretty
small.

yah - the above is where we got into trouble in fedora - b/c the sheer
volume of updates is a bit crushing if we tried to tack them on the end
of the xml. This is part of the reason to looking at pure-sqlite repos
so we could do all updates as just insert/deletes + repomd.xml
regeneration.
