I would like to note that the old-fashioned way to shut down -- letting
`s6-svscan' exec() into a "stage-3" script, which performs the halting
procedure -- is still available from slew and legacy s6-linux-init.
I personally find it simpler to understand, in the cost of a lack of
full compatibility with `shutdown' without relying on some `atd':
