Set /home/jovyan as read only for jovyan user

Because of the architecture of our system, files under /home/jovyan will not be saved, so it is important that the users will not be able to create and save files there

We have multiple subdirectories under /home/jovyan so I cannot set one of them to the root of the server :frowning:

Also in any case, even if the directory changes I want to also back this up permission wise - so that even if a user mistakenly tries to save a file, he won’t be able to
