Path should include binary itself, like /sbin/shutdown

What really puzzles me: Why would you want to shutdown the router?

When I decided to build my own network, I devised every type of appliance to work in shifts. There are mainly triggered by internal clock (or “WoL”) to start the shift and break with an internal “cron” job. I’m also always looking for hardware with the right scheduling features.
I therefore have peace of mind that for every appliance there is a backup ready to take the place automatically if a ping test fails, for example.
