Only use this if you really need it, on further inspection writing a systemd watchdog would be a better choice for libreelec et all (no idea why they use systemd, but whatever)


hardware watchdog for kodi 
(actually just libreelec, on multiuser oses surely a service supervisor can supervise kodi?)

writes to /dev/watchdog0 every 5 seconds or so, the machine should reboot if that doesn't happen (may need stuff in config.txt if you try this on raspberries)

requires correct linux kernel module to be loaded


assuming this even can be licensed i choose 0BSD
