IIRC, it is init(8) that prints this final message and not the loader.

Right...

if you look at /usr/src/sbin/init/init.c, you'll see that init(8) builds
with -DDEBUGSHELL.  Removing this from the Makefile and rebuilding
/sbin/init disabled the prompt for a shell and will just fire up /bin/sh
(or whatever _PATH_BSHELL was when /sbin/init was built).
