How to use alternative users after this fix? We use the container with multiple users and a mounted volume to the /home folder. Since every user has its own username, she/he gets its own folder for saving user preferences and credentials. The preferences are saved on the mounted volume and are loaded the next time of usage. How to recreate this situation after this fix?

I don't understand your question. I don't think it has anything to do with this change.
We recommend asking questions on Stack Overflow, etc.

Thank you for your response, the question is posted here: stackoverflow

I really don't know what you are trying to achieve, but if you want to change the username, the steps are described in the documentation in this repository.
