The current behavior of runit's halt is that options -d -h -p -i
are ignored except that a warning is printed (the exit status is zero).
They are not really noop, since in the original sysvinit implementation
each of -d -h -p -i imply halting/poweroff the system, so that's what
runit's halt does after "ignoring" such options.
I've tested in the past that if I turn -d -h -p -i into noop
the switch sysvinit --> runit-init is broken, so I don't want to do
What is left on runit's side is that I can silence the warning (but I
don't think is a good behavior for a program to silently ignore some
options - it can be documented in the man page though) or add a special
case in 'run_sysv_script' so that 'reboot' and 'halt' scripts are
skipped during runit shutdown sequence.

Runit is currently borrowing from sysvinit (initscripts package)
scripts to initialize and shutdown the system; it runs sequentially
scripts from /etc/rcS.d/ to boot the system and scripts from /etc/rc0.d/
or /etc/rc6.d/ for shutdown/reboot.

I think reassigning this to runit as Debian bug with severity minor is
