## s6-linux-init-shutdownd never tells s6-svscan to exit, so if
## you're running s6-linux-init, it's normal that your
## .s6-svscan/finish script is not executed.
## The place where you want to hack things is /etc/rc.shutdown.final,
## which is run by the stage 4 script right before the hard reboot.
## So you can do dirty stuff [...] which should clean up the
## s6-supervise and the foreground, and give control to
## .s6-svscan/finish.
