User's `$HOME` in JupyterHub

JupyterHub
3

Thanks @betatim - do I understand correctly that the workflow to get a pre-configured $HOME in JupyterHub with a custom repo2docker image is following:

repo2docker --target-repo-dir /home_commons ...

Then, in the JupyterHub config.yaml, use a post start copy command:

singleuser:
  lifecycleHooks:
    postStart:
      exec:
        command: ["cp", "-r", "/home_commons/*", "/home/joyvan/"]

Is that the way to go?
