So don't use util-linux's shutdown :-)

/etc/runit/stopit, /etc/runit/reboot and /etc/runit/3 should do all.

I'd guess that is because getty is responding correctly to the TERM 
signal, but whatever you replace getty with (login, or a successor) does 
not.

Yes and no. All you can do is give the session leader a HUP or TERM
signal. You want it to respond appropriately to that signal, and tidy
everything up and then exit. But it could just ignore the signal, in which
case you need a bigger hammer (e.g. a QUIT signal, or -9).

Those scripts won't necessarily be run when you want them to.
