Which is why /rescue/init is on the fallback init path, and can be explicitly
entered at the loader prompt.  Right now it is:
kern.init_path: /sbin/init:/sbin/oinit:/sbin/init.bak:/stand/sysinstall

And nothing would be stopping somebody from typing this at the loader:
set kern.init_path=/rescue/init
and at the shell path prompt, /rescue/sh

Cheers,
