[racket] easiest way to build from updated source with all packages?

I have a fork of Racket, so it used to be I could update to the current version by doing this:

git pull --ff-only upstream master

Then I would get all the updates to Racket + core packages.

Now, of course, with the repo split, the above command only pulls in updates to Racket itself.

What is the simplest way to amend my build command to behave the way it used to?

git pull --ff-only upstream master
raco pkg update --all

?
