Potentially helpful instructions for setting up fishnet to start automatically

[sAlexander]

Hi niklasf,

Thank you for your work on fishnet! I appreciate all the energy you put into the project.

I just finished setting up fishnet on my computer, and I wanted to share the instructions that I used in case they're helpful for others. I run Ubuntu 20.04.2 LTS, but I would expect the instructions to work for computer with systemd.

Feel free to ignore/close this issue if the instructions are too specific to my system or not generally useful; you know the fishnet users better than I do!

# Create a fishnet user. The user is created as a sysytem user
# meaning that they will not show up on your log-in screen.
sudo adduser \
    --system \
    --shell /bin/bash \
    --gecos ‘User for running fishnet’ \
    --group \
    --disabled-password \
    --home /home/fishnet \
    fishnet
    
# Log in as the fishnet user.
sudo -s -u fishnet

# Download the latest fishnet to /home/fishnet.
wget {LATEST FROM https://github.com/niklasf/fishnet/releases}

# Run fishnet once to create the configuration file.
/home/fishnet/fishnet-x86_64-unknown-linux-gnu --auto-update

#
# Exit out of the fishnet user with ctrl-D
#

# Create a fishnet service in systemd.
# Once enabled, the service will run fishnet when the
# system boots. If fishnet fails for some reason, it will
# attempt to restart fishnet up to 5 times.
sudo bash -c "cat >> /etc/systemd/system/fishnet.service" << EOL

Hi, thanks. Check out sudo -u fishnet /home/fishnet/fishnet-x86_64-unknown-linux-gnu systemd --auto-update. It has some improvements for your service file.

That's great, thank you!
