qmcrover.service is an example systemd 'unit' file to start qmmcrover
(using EGLFS, not X11) at boot via systemd.  To do this:

There must be a valid /usr/local/etc/mcroverd.cfg file on the localhost,
so that qmcrover knows where to get alerts.

The 'User' must have a valid keyset (id_ed25519[.pub]) and known_services
in their .dwmauth directory.  Edit the qmcrover.service file as desired.

After editing qmcrover.service, copy the service file into place:

  cp qmcrover.service /lib/systemd/system/qmcrover.service

Tell systemd to look for our service file:

  sudo systemctl daemon-reload

And enable qmcrover at boot:

  sudo systemctl enable qmcrover.service
