I like the idea of a separate bootstrap repo.

Even better would be a void-packges hierarchy that defines destination repositories instead of a repository template argument. For example: move all repository=nonfree templates under nonfree rather than srcpkgs, move the new repository=bootstrap templates under bootstrap, and we could even do away with restricted by creating a restricted hierarchy.

All of this is out of scope for this proposal, but I can dream.

files to be moved to their respective bootstrap repos (/current{,/bootstrap}, /current/aarch64{,/bootstrap}, /current/multilib{,/bootstrap}, /current/musl{,/bootstrap}): bootstrap-files.txt
