As I indicated in the other thread, this is the route I plan to take.

Sounds good. As I indicated in the other thread, I think updates in
Fedora can be handled using side tags[2]:

 1. build updated [lib]build2 first into a side tag
 2. build updated libbuild2-kconfig against libbuild2 in same side tag
 3. push side tag packages to updates
