FWIW I had to do the latter the other day to check which stable branches
needed distinct backports. Since git series doesn't seem to allow
"forking" of a series yes (i.e. analagous to git checkout -b b1 b2), i
ended up doing something along the lines of this repeatedly:

git branch git-series/$feature/stable/4.7 git-series/$feature/staging
git series checkout git-series/$feature/stable/4.7
git series rebase v4.7
etc

(so the new series inherits / branches the history of the old one)

So it'd be nice to be able to do something like this instead:
git series checkout -b new_series [old_series = current_series]
git series rebase v4.7

Cheers
