Send the runsvdir process a TERM signal, so that stage 2 exits cleanly.
runit will then enter stage 3.
runsvdir(8):
SIGNALS
If runsvdir receives a TERM signal, it exits with 0 immediately.
runit(8):
STAGE 2
runit runs /etc/runit/2, which should not return until system
shutdown; if it crashes, or exits 111, it will be restarted.
IIRC 'reboot -f' doesn't do anything with the init process, but simply
hard-reboots the machine, I posted a simple program that also does that
here

HTH, Gerrit.
