I find this change tricky to review, I lack too much knowledge about how things are supposed to work and such.

I hope someone else can review it for now. Note that there is a merge conflict related to the change introduced in #511.

It's quite an old issue. Based on the name of the directory /opt/tljh/user/bin I'd have thought it's only for the user environment not the system environment, which implies it shouldn't be set globally.

I don't believe the user env should be on the path for running tljh. At least it shouldn't be ahead of the hub env. This PR only changes the env for the test Dockerfile, not in a place that would affect actual installs.

I think both this and #412 can be closed. This issue is covered in the docs. If anything, we could add more detail about explicitly installing in the user env independent of $PATH at the time, e.g.:

conda install -p /opt/tljh/user PACKAGE
/opt/tljh/user/bin/pip install PACKAGE
