Then, work on the tip of the topic branch you depend on instead of pu. These are more stable, as they will be rewritten only if this particular topic branch changes.

Yes. If you insist in working on top of pu, you can rebase --onto origin/pu.

That would be "git fetch" and then "git rebase", as I don't think "git pull --rebase" would allow you to specify the starting point for rebase.

This is conceptually similar to what "git rebase" does, but it does it in a slightly more efficient way ;-).
