such as ?
what more information than the runlevel (0 or 6, maybe 1 to go
into single user) does SysV init need to start the system shutdown ?
and shutdown itself just notifies all users via wall, logs shutdown time
to wtmp and then notifies init via the /dev/.initctl fifo.
this can all be done solely by 2 different signals.

the Void Linux team just made a shell script out of it that just brings
down the runit services and runsvdir itself.
