The cleanup job now restores the whole home directory instead of only
the four text files: the directory itself, the shell configuration that
gives the prompt, and the files. Anything that is not a regular file is
replaced, so the files stay text files.
The README in server/ describes the security model: the box is a
disposable VPS that may be compromised, the root user may do whatever
they want, and only the prompt, the home directory and the four files
are kept working.
