Bug#928110: Teeworlds server fails to start because of missing directory

[Baptiste Jonglez]

Package: teeworlds-server
Version: 0.7.2-3

I installed teeworlds-server on a fresh installation of buster and
followed the instructions in the README:

    # adduser --force-badname _teeworlds
    # systemctl enable teeworlds-server
    # systemctl start teeworlds-server

However, the teeworlds server failed to start:

    Apr 28 12:28:21 teeworlds systemd[1]: teeworlds-server.service: Succeeded.

The problem is that the "/home/_teeworlds/.local/share/teeworlds"
directory does not exist.  Creating it fixed the issue:

    # su - _teeworlds -c 'mkdir -p /home/_teeworlds/.local/share/teeworlds'

This directory either needs to be created automatically, or additional
instructions should be added to the README.

Thanks,
