### ToDo combine the following parts for better building
## Customizing console
RUN echo "alias ll='ls -lah --color=auto'" >> /root/.bashrc

## Setting timezone
RUN cp /usr/share/zoneinfo/Europe/Berlin /etc/localtime \
    && echo "Europe/Berlin" > /etc/timezone

## add user fhem, copy some files from github instead of using docker context
