I set my CI, so that it does not allow concurrent builds from the same
job. So there are no race conditions. This is probably possible with
Travis, I don't know.

So far I didn't, and only pushed back "main" branch. But you can just
push back to different branches. In this case I would probably create
another repo, and have the same branches in both in the "source" repo
and the "publish" repo.

I am just using make to create the package. This creates all
autogenerated files and then calls R PKG build.

Another option for this whole problem is not using github at all, but
setting up a CRAN-like repository, and make the CI publish the built
and checked packages there.
