# * A link named emulationstation pointing to the ES executable must be in the

# * reboot and poweroff are symlinks to systemctl. systemd only allows to
#   shutdown the system to logged in users. This is the reason those
#   commands cannot be used in this script. DBus must be used
#   for rebooting/powering off.
