The home dir should be '/root', not '/home/root', when starting the container and set the env 'NB_USER' to 'root'.

What docker image(s) are you using?

base-notebook

Host OS system

ubuntu 23.10

Host architecture

x86_64

What Docker command are you running?

docker run --rm --user root -p 8888:8888 -e JUPYTER_TOKEN=123 -e NB_UID=0 -e NB_GID=0 -e NB_USER=root jupyter/base-notebook:notebook-7.0.2 /usr/local/bin/start-notebook.sh --allow-root

How to Reproduce the problem?

1. Run the following command

docker run --rm --user root -p 8888:8888 -e JUPYTER_TOKEN=123 -e NB_UID=0 -e NB_GID=0 -e NB_USER=root jupyter/base-notebook:notebook-7.0.2 /usr/local/bin/start-notebook.sh --allow-root

2. After the container starts, the logs contain the following information:

Entered start.sh with args: jupyter lab --allow-root
Running hooks in: /usr/local/bin/start-notebook.d as uid: 0 gid: 0
Done running hooks in: /usr/local/bin/start-notebook.d
Updated the jovyan user:
- username: jovyan       -> root
- home dir: /home/jovyan -> /home/root
Attempting to copy /home/jovyan to /home/root...
Success!
Changing working directory to /home/root/
Running hooks in: /usr/local/bin/before-notebook.d as uid: 0 gid: 0
Done running hooks in: /usr/local/bin/before-notebook.d
Running as root: jupyter lab --allow-root

The logs indicate that the home directory has been set to '/home/root' instead of '/root'.

Command output

Entered start.sh with args: jupyter lab --allow-root
Running hooks in: /usr/local/bin/start-notebook.d as uid: 0 gid: 0
Done running hooks in: /usr/local/bin/start-notebook.d
Updated the jovyan user:
- username: jovyan       -> root
- home dir: /home/jovyan -> /home/root
Attempting to copy /home/jovyan to /home/root...

Changing working directory to /home/root/
Running hooks in: /usr/local/bin/before-notebook.d as uid: 0 gid: 0
Done running hooks in: /usr/local/bin/before-notebook.d
Running as root: jupyter lab --allow-root
`

Expected behavior

The home dir should be '/root', not '/home/root', when starting the container and set the env 'NB_USER' to 'root'.

Actual behavior

When setting the NB_USER as 'root', the home dir should be '/root'.

@orange-guo See #2039 for an ongoing discussion.

IMHO we do not want to use (and touch) the original /root directory.

For my explanation, see #2039 (comment) ff.
