Workflow for fetching new Gerrit patchsets

[jakubsmolaga]

Hi, I recently started using jj at work and I think I might be a little bit confused about dealing with Gerrit. Here is my current workflow:

1. Colleague pushes a new version of a change
2. I run git fetch ssh://<...> refs/changes/<...> && git checkout FETCH_HEAD
3. The change appears in jj but it has a different jj change id
4. Rebase all children of the old change onto the new change
5. Abandon the old change

Is this the correct way to do this? If not, what would be the idiomatic way of getting a new patchset? Thanks :)
