I handle it by _not_ informing init at all. Why should I?
I kill all daemons and remount all fs ro. Now I can reboot/shut down
without bothering about init.

If your init respawns daemons... well... you've got wrong init.
I spawn e.g. getties from svscan, not init. svscan is -TERM'able.

After I've done that, I realized that I don't need specially crafted init
at all, and replaced it with a shell script. Unexpectedly, nothing broke.
